NPOI创建DOCX常用操作
1、 创建文档
XWPFDocument m_Docx = new XWPFDocument();
2、 页面设置
//1‘=1440twip=25.4mm=72pt(磅point)=96px(像素pixel)
//1px(像素pixel)=0.75pt(磅point)
// A4:W=11906 twip=8.269''=210mm,h=16838twip=11.693''=297mm
//A5:W=8390 twip=5.827''=148mm,h=11906 twip=8.269''=210mm
//A6:W=5953 twip=4.134''=105mm,h=8390twip=5.827''=1148mm
//16k195mmX270mm:
//16k184mmX260mm:
//16k197mmX273mm:
CT_SectPr m_SectPr = newCT_SectPr();
//页面设置A4横向
m_SectPr.pgSz.w = (ulong)16838;
m_SectPr.pgSz.h = (ulong)11906;
m_Docx.Document.body.sectPr = m_SectPr;
3、 创建段落
1) XWPFParagraph gp = m_Docx.CreateParagraph();
2) CT_Pm_p = m_Docx.Document.body.AddNewP();
m_p.AddNewPPr().AddNewJc().val = ST_Jc.center;//段落水平居中
XWPFParagraph gp = newXWPFParagraph(m_p, m_Docx); //创建XWPFParagraph
4、 段首行缩进
gp.IndentationFirstLine=(int)100；
可以用一个函数计算
protected int Indentation(Stringfontname, int fontsize, int Indentationfonts, FontStylefs)
{
//字显示宽度，用于段首行缩进
//字号与fontsize关系
//初号（0号）=84，小初=72，1号=52，2号=44，小2=36，3号=32，小3=30，4号=28，
//小4=24，5号=21，小5=18，6号=15，小6=13，7号=11，8号=10
Graphicsm_tmpGr = this.CreateGraphics();
m_tmpGr.PageUnit = GraphicsUnit.Point;
SizeF size = m_tmpGr.MeasureString("好", new Font(fontname,fontsize * 0.75F, fs));
return (int)size.Width* Indentationfonts * 10;
}
gp.IndentationFirstLine= Indentation("宋体", 21, 2, FontStyle.Regular);//段首行缩进2字符
5、 行距设置
//单倍为默认值（240twip）不需设置，1.5倍=240X1.5=360twip，2倍=240X2=480twip
m_p.AddNewPPr().AddNewSpacing().line = "400";//行距固定20磅
m_p.AddNewPPr().AddNewSpacing().lineRule= ST_LineSpacingRule.exact;
6、 创建RUN
1) XWPFRun gr= gp.CreateRun();
gr.GetCTR().AddNewRPr().AddNewRFonts().ascii = "黑体";
gr.GetCTR().AddNewRPr().AddNewRFonts().eastAsia = "黑体";
gr.GetCTR().AddNewRPr().AddNewRFonts().hint = ST_Hint.eastAsia;
gr.GetCTR().AddNewRPr().AddNewSz().val = (ulong)44;//2号字体
gr.GetCTR().AddNewRPr().AddNewSzCs().val = (ulong)44;
gr.GetCTR().AddNewRPr().AddNewB().val = true;//加粗
gr.GetCTR().AddNewRPr().AddNewColor().val= "red";//字体颜色
gr.SetText("DOCX表");
2) CT_R= m_p.AddNewR();
7、 创建表
1） 创建表
有两种方法：
a.方法1
XWPFTabletable = m_Docx.CreateTable(1, 1);//创建1行1列表
CT_Tblm_CTTbl = m_Docx.Document.body.GetTblArray()[0];//获得文档第一张表
b.方法2
CT_Tblm_CTTbl = m_Docx.Document.body.AddNewTbl();
XWPFTabletable = new XWPFTable(m_CTTbl,m_Docx);//创建1行1列表
2） 表水平居中
m_CTTbl.AddNewTblPr().jc = new CT_Jc();
m_CTTbl.AddNewTblPr().jc.val = ST_Jc.center;//表在页面水平居中
3） 表宽度
m_CTTbl.AddNewTblPr().AddNewTblW().w = "2000";//表宽度
m_CTTbl.AddNewTblPr().AddNewTblW().type = ST_TblWidth.dxa;
4） 表定位
//若tblpXSpec、tblpX同时存在，则tblpXSpec优先tblpX；
//若tblpYSpec、tblpY同时存在，则tblpYSpec优先tblpY；
m_CTTblPr.tblpPr = new CT_TblPPr();//表定位
m_CTTblPr.tblpPr.tblpX = "4003";//表左上角坐标
m_CTTblPr.tblpPr.tblpY = "365";
//m_CTTblPr.tblpPr.tblpXSpec = ST_XAlign.center;// tblpXSpec优先tblpX
//m_CTTblPr.tblpPr.tblpYSpec = ST_YAlign.top;// tblpYSpec优先tblpY
m_CTTblPr.tblpPr.leftFromText = (ulong)180;
m_CTTblPr.tblpPr.rightFromText = (ulong)180;
m_CTTblPr.tblpPr.vertAnchor = ST_VAnchor.text;
m_CTTblPr.tblpPr.horzAnchor = ST_HAnchor.page;
5） 列宽设置
//列宽设置
CT_TcPr m_Pr =table.GetRow(0).GetCell(0).GetCTTc().AddNewTcPr();
m_Pr.tcW = new CT_TblWidth();
m_Pr.tcW.w = "1500";//单元格宽
m_Pr.tcW.type = ST_TblWidth.dxa;
m_Pr = table.GetRow(0).GetCell(1).GetCTTc().AddNewTcPr();
m_Pr.tcW = new CT_TblWidth();
m_Pr.tcW.w = "1000";//单元格宽
m_Pr.tcW.type = ST_TblWidth.dxa;
6） 创建行
a. XWPFTableRow m_Row = table.CreateRow();//创建一行
b. XWPFTableRow m_Row = table.InsertNewTableRow(0);//表头插入一行
c. XWPFTableRow td3 = table.InsertNewTableRow(table.Rows.Count - 1);//插入行
d. CT_Row m_NewRow = new CT_Row();
XWPFTableRow m_Row = new XWPFTableRow(m_NewRow, table);
table.AddRow(m_Row);
7） 行高设置
a. m_Row.GetCTRow().AddNewTrPr().AddNewTrHeight().val= (ulong)426;
b. m_NewRow.AddNewTrPr().AddNewTrHeight().val= (ulong)426;
8） 创建单元格
a. XWPFTableCell cell = m_Row.CreateCell();//创建一单元格,创建单元格时就创建了一个CT_P
b. XWPFTableCell cell = m_Row.AddNewTableCell();//创建单元格时创建了一个CT_P
9） 单元格设置文字
table.GetRow(0).GetCell(0).SetText("111");
10） 列合并
//表增加行，合并列
CT_Row m_NewRow = new CT_Row();
XWPFTableRow m_Row = new XWPFTableRow(m_NewRow,table);
table.AddRow(m_Row);
XWPFTableCell cell = m_Row.CreateCell();
CT_Tc cttc = cell.GetCTTc();
CT_TcPr ctPr = cttc.AddNewTcPr();
ctPr.gridSpan = new CT_DecimalNumber();
ctPr.gridSpan.val = "3"; //合并3列
cttc.GetPList()[0].AddNewPPr().AddNewJc().val = ST_Jc.center;
cttc.GetPList()[0].AddNewR().AddNewT().Value = "sss";
11） 行合并
//1行
CT_Row m_NewRow = new CT_Row();
XWPFTableRow m_Row = new XWPFTableRow(m_NewRow,table);
table.AddRow(m_Row);
XWPFTableCell cell = m_Row.CreateCell();
CT_Tc cttc = cell.GetCTTc();
CT_TcPr ctPr = cttc.AddNewTcPr();
ctPr.AddNewVMerge().val = ST_Merge.restart;//合并行
ctPr.AddNewVAlign().val = ST_VerticalJc.center;//垂直
cttc.GetPList()[0].AddNewPPr().AddNewJc().val = ST_Jc.center;
cttc.GetPList()[0].AddNewR().AddNewT().Value = "xxx";
//2行，多行合并类似
m_NewRow = new CT_Row();
m_Row = new XWPFTableRow(m_NewRow,table);
table.AddRow(m_Row);
cell = m_Row.CreateCell();
cttc = cell.GetCTTc();
ctPr = cttc.AddNewTcPr();
ctPr.AddNewVMerge().val = ST_Merge.@continue;//合并行
8、 插图
1） 内联式插图(inline)
此种插图方式对插入的图片位置不能灵活控制，只能通过段设置，对应word的嵌入型插图。宽和高数值换算：1cm=360000 EMUS（English Metric Unit）。
FileStream gfs = null;
gfs = new FileStream("f:\pic\1.jpg", FileMode.Open, FileAccess.Read);
m_p = m_Docx.Document.body.AddNewP();
m_p.AddNewPPr().AddNewJc().val = ST_Jc.center;//段落水平居中
gp = new XWPFParagraph(m_p,m_Docx);
gr = gp.CreateRun();
gr.AddPicture(gfs, (int)NPOI.XWPF.UserModel.PictureType.JPEG, "1.jpg",1000000, 1000000);
gfs.Close();
2） 锚式插图(anchor)
此种插图方式对插入的图片位置能灵活控制，对应word的四周型、紧密型、穿越型等。图的左上角坐标及宽和高数值换算：1cm=360000 EMUS（English Metric Unit）。
gfs = new FileStream("f:\pic\1.jpg", FileMode.Open, FileAccess.Read);
m_p = m_Docx.Document.body.AddNewP();
m_p.AddNewPPr().AddNewJc().val = ST_Jc.center;
gp = new XWPFParagraph(m_p,m_Docx);
gr = gp.CreateRun();
CT_Anchor an = newCT_Anchor();
//图片距正文上(distT)、下(distB)、左(distL)、右(distR)的距离。114300EMUS=3.1mm
an.distB = (uint)(0);
an.distL = 114300u;
an.distR = 114300U;
an.distT = 0U;
an.relativeHeight = 251658240u;
an.behindDoc = false; //"0"，图与文字的上下关系
an.locked = false; //"0"
an.layoutInCell = true; //"1"
an.allowOverlap = true; //"1"
CT_Positive2D simplePos = new CT_Positive2D();
simplePos.x = (long)0;
simplePos.y = (long)0;
CT_EffectExtent effectExtent = new CT_EffectExtent();
effectExtent.b = 0L;
effectExtent.l = 0L;
effectExtent.r = 0L;
effectExtent.t = 0L;
//图左上角坐标
CT_PosH posH = newCT_PosH();
posH.relativeFrom = ST_RelFromH.column;
posH.posOffset = 4000000;//单位：EMUS，1CM=360000EMUS
CT_PosV posV = newCT_PosV();
posV.relativeFrom = ST_RelFromV.paragraph;
posV.posOffset = 200000;
a) 四周型
CT_WrapSquare wrapSquare = new CT_WrapSquare();
wrapSquare.wrapText = ST_WrapText.bothSides;
gr.AddPicture(gfs, (int)NPOI.XWPF.UserModel.PictureType.JPEG, "1.jpg",1000000, 1000000,
posH, posV, wrapSquare,anchor,simplePos,effectExtent);
b) 紧密型
CT_WrapTight wrapTight = new CT_WrapTight();
wrapTight.wrapText = ST_WrapText.bothSides;
wrapTight.wrapPolygon = new CT_WrapPath();
wrapTight.wrapPolygon.edited = false;
wrapTight.wrapPolygon.start = new CT_Positive2D();
wrapTight.wrapPolygon.start.x = 0;
wrapTight.wrapPolygon.start.y = 0;
CT_Positive2D lineTo = new CT_Positive2D();
wrapTight.wrapPolygon.lineTo = new List<CT_Positive2D>();
lineTo = new CT_Positive2D();
lineTo.x = 0;
lineTo.y = 21394;
wrapTight.wrapPolygon.lineTo.Add(lineTo);
lineTo = new CT_Positive2D();
lineTo.x = 21806;
lineTo.y = 21394;
wrapTight.wrapPolygon.lineTo.Add(lineTo);
lineTo = new CT_Positive2D();
lineTo.x = 21806;
lineTo.y = 0;
wrapTight.wrapPolygon.lineTo.Add(lineTo);
lineTo = new CT_Positive2D();
lineTo.x = 0;
lineTo.y = 0;
wrapTight.wrapPolygon.lineTo.Add(lineTo);
gr.AddPicture(gfs, (int)NPOI.XWPF.UserModel.PictureType.JPEG, "1.jpg",720000, 720000,
posH, posV, wrapTight, anchor, simplePos, effectExtent);
c) 穿越型
CT_WrapThrough wrapThrough = new CT_WrapThrough();
wrapThrough.wrapText = ST_WrapText.bothSides;
wrapThrough.wrapPolygon = new CT_WrapPath();
wrapThrough.wrapPolygon.edited = false;
wrapThrough.wrapPolygon.start = new CT_Positive2D();
wrapThrough.wrapPolygon.start.x = 0;

gr.AddPicture(gfs, (int)NPOI.XWPF.UserModel.PictureType.JPEG, "1.jpg",720000, 720000,
posH, posV, wrapThrough, anchor, simplePos, effectExtent);
9、 页眉页脚设置
1） 页眉设置
XWPFDocument m_Docx = new XWPFDocument();
m_Docx.Document.body.sectPr = new CT_SectPr();
CT_SectPr m_SectPr =m_Docx.Document.body.sectPr;
//创建页眉
CT_Hdr m_Hdr = new CT_Hdr();
m_Hdr.AddNewP().AddNewR().AddNewT().Value = "hhh";//页眉内容
//创建页眉关系（headern.xml）
XWPFRelation Hrelation = XWPFRelation.HEADER;
XWPFHeader m_h = (XWPFHeader)m_Docx.CreateRelationship(Hrelation,XWPFFactory.GetInstance(),
m_Docx.HeaderList.Count + 1);
//设置页眉
m_h.SetHeaderFooter(m_Hdr);
CT_HdrFtrRef m_HdrFtr =m_SectPr.AddNewHeaderReference();
m_HdrFtr.type = ST_HdrFtr.@default;
m_HdrFtr.id = m_h.GetPackageRelationship().Id;
2） 页脚设置
XWPFDocument m_Docx = new XWPFDocument();
//页面设置
m_Docx.Document.body.sectPr = new CT_SectPr();
CT_SectPr m_SectPr =m_Docx.Document.body.sectPr;
//创建页脚
CT_Ftr m_ftr = new CT_Ftr();
m_ftr.AddNewP().AddNewR().AddNewT().Value = "fff";//页脚内容
//创建页脚关系（footern.xml）
XWPFRelation Frelation = XWPFRelation.FOOTER;
XWPFFooter m_f = (XWPFFooter)m_Docx.CreateRelationship(Frelation,XWPFFactory.GetInstance(),
m_Docx.FooterList.Count + 1);
//设置页脚
m_f.SetHeaderFooter(m_ftr);
CT_HdrFtrRef m_HdrFtr =m_SectPr.AddNewFooterReference();
m_HdrFtr.type = ST_HdrFtr.@default;
m_HdrFtr.id = m_f.GetPackageRelationship().Id;
10、 脚注尾注
创建脚注和尾注，首先要设置格式，其次创建脚注和尾注内容，最后在正文中标注。
1） 格式设置
在正文中标注脚注采用阿拉伯数字且为上标，而标注尾注采用罗马数字且为上标，在word中可以事先用格式存储在格式xml中，以后可以在正文引用其格式即可。
创建格式文件（styles.xml）：XWPFStyles m_styles = m_Docx.CreateStyles();
创建格式xml：CT_Styles m_ctstyles = new CT_Styles();可以根据需要创建相应的格式。在此只列举与脚注有关的格式a6和a7。
格式a6设置如下，其中需要格式a和Char2。
//footnote text
m_ctstyle = new CT_Style();
m_ctstyle.type = ST_StyleType.paragraph;
m_ctstyle.customStyle = ST_OnOff.True;
m_ctstyle.styleId = "a6";
m_ctstyle.name = new CT_String();
m_ctstyle.name.val = "footnotetext";
m_ctstyle.basedOn = new CT_String();
m_ctstyle.basedOn.val = "a";
m_ctstyle.link = new CT_String();
m_ctstyle.link.val = "Char2";
m_ctstyle.uiPriority = new CT_DecimalNumber();
m_ctstyle.uiPriority.val = "99";
m_ctstyle.semiHidden = new CT_OnOff();
m_ctstyle.semiHidden.val = true;
m_ctstyle.unhideWhenUsed = new CT_OnOff();
m_ctstyle.unhideWhenUsed.val = true;
m_ctstyle.rsid = new CT_LongHexNumber();
byte[] m_bytefootnoteText = { 0x00, 0xF0, 0x43, 0x96};
m_ctstyle.rsid.val = m_bytefootnoteText;
m_ctstyle.pPr = new CT_PPr();
m_ctstyle.pPr.snapToGrid = new CT_OnOff();
m_ctstyle.pPr.snapToGrid.val= false;
m_ctstyle.pPr.jc = new CT_Jc();
m_ctstyle.pPr.jc.val = ST_Jc.left;
m_ctstyle.rPr = new CT_RPr();
m_ctstyle.rPr.sz = new CT_HpsMeasure();
m_ctstyle.rPr.sz.val = 18;
m_ctstyle.rPr.szCs = new CT_HpsMeasure();
m_ctstyle.rPr.szCs.val = 18;
m_ctstyles.style.Add(m_ctstyle);
格式a7设置如下，其中需要格式a0。
//footnote reference
m_ctstyle = new CT_Style();
m_ctstyle.type= ST_StyleType.character;
m_ctstyle.styleId = "a7";
m_ctstyle.name = new CT_String();
m_ctstyle.name.val = "footnotereference";
m_ctstyle.basedOn = new CT_String();
m_ctstyle.basedOn.val= "a0";
m_ctstyle.uiPriority = new CT_DecimalNumber();
m_ctstyle.uiPriority.val = "99";
m_ctstyle.semiHidden = new CT_OnOff();
m_ctstyle.semiHidden.val = true;
m_ctstyle.unhideWhenUsed = new CT_OnOff();
m_ctstyle.unhideWhenUsed.val = true;
m_ctstyle.rsid = new CT_LongHexNumber();
m_ctstyle.rsid.val = m_bytefootnoteText;
m_ctstyle.rPr = new CT_RPr();
m_ctstyle.rPr.vertAlign = new CT_VerticalAlignRun();
m_ctstyle.rPr.vertAlign.val = ST_VerticalAlignRun.superscript;
m_ctstyles.style.Add(m_ctstyle);
把格式添加到格式文件中：m_styles.SetStyles(m_ctstyles);
2） 脚注
a. 创建脚注内容
实际上脚注内容的格式就是引用前面所述的格式设置中的定义，即格式a6和a7。
创建脚注内容文件：XWPFFootnotes m_ftns =m_Docx.CreateFootnotes()。
//创建脚注内容
int Id =m_ftns.GetFootnotesList().Count;
CT_FtnEdn m_ftnedn = new CT_FtnEdn();
m_ftnedn.id = Id.ToString();
CT_P m_FtnEdnxmlP =m_ftnedn.AddNewP();
CT_PPr m_FtnEdnxmlPPr =m_FtnEdnxmlP.AddNewPPr();
m_FtnEdnxmlPPr.AddNewPStyle().val = "a6";
m_FtnEdnxmlPPr.AddNewRPr().rFonts = new CT_Fonts();
m_FtnEdnxmlPPr.AddNewRPr().rFonts.hint = ST_Hint.eastAsia;
CT_R m_FtnEdnxmlR =m_FtnEdnxmlP.AddNewR();
m_FtnEdnxmlR.AddNewRPr().rStyle = new CT_String();
m_FtnEdnxmlR.AddNewRPr().rStyle.val = "a7";
m_FtnEdnxmlR.Items = newSystem.Collections.ArrayList();
m_FtnEdnxmlR.Items.Add(new CT_Empty());
m_FtnEdnxmlR.ItemsElementName = new List<RunItemsChoiceType>();
m_FtnEdnxmlR.ItemsElementName.Add(RunItemsChoiceType.footnoteRef);
m_FtnEdnxmlR = m_FtnEdnxmlP.AddNewR();
m_FtnEdnxmlR.AddNewT().Value = " ";
m_FtnEdnxmlR = m_FtnEdnxmlP.AddNewR();
m_FtnEdnxmlR.AddNewT().Value = strFtnEdn; //"脚注test内容
XWPFFootnotem_fn = m_ftns.AddFootnote(m_ftnedn);
b. 在正文中标注
最好用CT_P m_p = m_Docx.Document.body.AddNewP();方式创建段，在m_p中可以不断创建CT_R。
CT_R m_r = m_p.AddNewR();
m_r.AddNewT().Value = "NPOI";
//标注脚注
CT_R m_FtnEdnR = m_p.AddNewR();
m_FtnEdnR.AddNewRPr().rStyle= new CT_String();
m_FtnEdnR.AddNewRPr().rStyle.val = "a7";
m_FtnEdnR.Items = newSystem.Collections.ArrayList();
CT_FtnEdnRef m_ftnref = newCT_FtnEdnRef();
m_ftnref.id = m_FtnId;//创建脚注内容得到的Id
m_FtnEdnR.Items.Add(m_ftnref);
m_FtnEdnR.ItemsElementName = new List<RunItemsChoiceType>();
m_FtnEdnR.ItemsElementName.Add(RunItemsChoiceType.footnoteReference);
m_r =m_p.AddNewR();
m_r.AddNewT().Value= "……";
3） 尾注
NPOI中的OpenXmlFormats提供了较为完善的尾注所有功能，但在XWPF中没有提供创建尾注的方法。
11、 超链接书签
利用NPOI创建超链接书签分两个步骤。一是创建与书签关联的超链接；二是创建书签。
1） 创建与书签关联的超链接
NPOI提供两种超链接，一种是超链接到另一文件；另一种是超链接到书签。下面仅介绍创建超链接到书签的方法。
创建文档：XWPFDocument m_Docx = new XWPFDocument();
创建段落：CT_P m_p = m_Docx.Document.body.AddNewP();
创建超链接集合：m_p.Items = newSystem.Collections.ArrayList();
创建超链接：
CT_Hyperlink1 m_hyperlink = new CT_Hyperlink1();
m_hyperlink.anchor = "NPOI1";//书签名
m_hyperlink.history = ST_OnOff.True;
m_hyperlink.Items = newSystem.Collections.ArrayList();
CT_R m_r = new CT_R();
m_r.AddNewT().Value = "书签1";
m_hyperlink.Items.Add(m_r);
m_hyperlink.ItemsElementName = new List<ItemsChoiceType12>();
m_hyperlink.ItemsElementName.Add(ItemsChoiceType12.hyperlink);
m_p.Items.Add(m_hyperlink);
2） 创建书签
书签分开始和结束两部分组成。
//书签0开始
int m_bookId = 0;//同一段内有多个书签，需要不同的Id，不同段的书签Id可以相同
m_p= m_Docx.Document.body.AddNewP();
m_p.AddNewPPr().AddNewJc().val= ST_Jc.both;
m_p.AddNewPPr().AddNewSpacing().line = "400";//固定行距20磅
m_p.AddNewPPr().AddNewSpacing().lineRule = ST_LineSpacingRule.exact;
m_p.Items = new System.Collections.ArrayList();
CT_Bookmark m_ctbook1 = newCT_Bookmark();
m_bookId = m_p.Items.Count;
m_ctbook1.id = m_bookId.ToString(); //"0";
m_ctbook1.name = "NPOI1";//书签名，超链接用
m_p.Items.Add(m_ctbook1);
m_p.ItemsElementName = new List<ParagraphItemsChoiceType>();
m_p.ItemsElementName.Add(ParagraphItemsChoiceType.bookmarkStart);
m_p.AddNewR().AddNewT().Value = "1、NPOI介绍";
//书签0结束
m_ctbook1 = new CT_Bookmark();
m_ctbook1.id = m_bookId.ToString();//"0";
m_p.Items.Add(m_ctbook1);
m_p.ItemsElementName.Add(ParagraphItemsChoiceType.bookmarkEnd);
12、 插入图表
在docx中插入图表分三步实现。一是创建xlsx格式的图表原始数据，二是创建图表类型，三是在正文中插入图表。每一个图表对应一个xlsx文件，下面以饼图为例说明。
1) 创建xlsx格式的图表原始数据
//创建xlsx
XSSFWorkbook workbook = newXSSFWorkbook();
//创建表单1（饼图）
I Sheet sheet =workbook.CreateSheet("Sheet1");
//表单1饼图数据
//销售额
//第一季度 8.2
//第二季度 3.2
//第三季度 1.4
//第四季度 1.2
IRow row = sheet.CreateRow(0);
ICell cell = row.CreateCell(0);
cell = row.CreateCell(0);
cell = row.CreateCell(1);
cell.SetCellValue("销售额");
row = sheet.CreateRow(1);
cell = row.CreateCell(0);
cell.SetCellValue("第一季度");
cell = row.CreateCell(1);
cell.SetCellValue(8.2);
row = sheet.CreateRow(2);
cell = row.CreateCell(0);
cell.SetCellValue("第二季度");
cell = row.CreateCell(1);
cell.SetCellValue(3.2);
row = sheet.CreateRow(3);
cell = row.CreateCell(0);
cell.SetCellValue("第三季度");
cell = row.CreateCell(1);
cell.SetCellValue(1.4);
row = sheet.CreateRow(4);
cell = row.CreateCell(0);
cell.SetCellValue("第四季度");
cell = row.CreateCell(1);
cell.SetCellValue(1.2);
2) 创建图表类型
//创建wordchartschartn.xml内容（简单饼图）
CT_ChartSpace ctpiechartspace = new CT_ChartSpace();
ctpiechartspace.date1904 = new CT_Boolean();
ctpiechartspace.date1904.val = 1;
ctpiechartspace.lang = new CT_TextLanguageID();
ctpiechartspace.lang.val = "zh-CN";
CT_Chart m_chart = ctpiechartspace.AddNewChart();
m_chart.plotArea = new CT_PlotArea();
m_chart.plotArea.pieChart = new List<CT_PieChart>();
//饼图
CT_PieChart m_piechart = new CT_PieChart();
m_piechart.varyColors = new CT_Boolean();
m_piechart.varyColors.val = 1;
m_piechart.ser = new List<CT_PieSer>();
CT_PieSer m_pieser = new CT_PieSer();
//标题
m_pieser.tx = new CT_SerTx();
m_pieser.tx.strRef = new CT_StrRef();

3) 页面中插入图表
以inline式为例。
XWPFParagraph gp = m_Docx.CreateParagraph();
XWPFRun gr = gp.CreateRun();
gp = m_Docx.CreateParagraph();
gr = gp.CreateRun();
gr.AddChartSpace(workbook , ctpiechartspace, 5274310, 3076575);
NPOI是tonyqus提供的2.1.1.0源码经过新修改编译。
