     * 请大家引用时保留这段作者声明,此代码为开源代码;使用不受限制,欢迎大家采用本人所写JS动态拖动表格实现代码。
     * JavaScript创建的可编辑表格
     * 用法:
     *    1,首先创建表格对象: var pt = new PowerTableEdit("table1");
     *                          其中,"table1"为表格的id
     *                         
     *    2,设置表格的编辑方式,调用pt对象的setCol方法,此方法有三个参数:
     *   
     *                          setCol(colNum,colSty,sDa)
     *                         
     *                          > colNum:为准备编辑的列编号,第一列编号为0
     *                          > colSty:为准备编辑的方式,txt为文本编辑方式,sel为下拉编辑方式
     *                          > sDa:如果选择的编辑方式为下拉编辑方式,则此参数有效,代表下拉框中的预置数据,是数组类型
     *                 
     *    3, 在按钮中调用相应的方法(注意:上移行和下移行按钮的id必须为moveUp和moveDown):如:
     *
     *      <!--增加行-->
     *      <input onclick=add_row(mainTab) type=button value=ins_row>
     *      <!--删除行-->
     *      <input onclick=del_row(mainTab) type=button value=Del_row>
     *      <!--重置表格-->
     *      <input onclick=res_tab() type=button value=Restore>
     *     
     *      <!--上移行-->
     *      <input id=moveUp onclick=Move_up(mainTab) type=button value=Up>
     *      <!--下移行-->      
     *      <input id=moveDown onclick=Move_down(mainTab) type=button value=Down>
     *    4, 如果想取消编辑功能,调用方法setEditable(false)
     *    5, 增加一行时,可以先调用selCellData方法,传入一个数组,来设置增加一行时没格单元格的数据
     *
     *    5,例如:
     *              var arr = new Array();
     *              arr[0] = "a";
     *              arr[1] = "b";
     *              arr[2] = "c";
     *             
     *              var arr1 = new Array();
     *              arr1[0] = "1";
     *              arr1[1] = "2";
     *              arr1[2] = "3";
     *             
     *              //页面table的id为table1
     *              var pt = new PowerTable("table1");
     *             
     *              //表格的第一列为文本编辑方式
     *              pt.setCol(0,'txt');
     *              //表格的第二列为下拉框编辑方式,指定数据为数组arr
     *              pt.setCol(2,'sel',arr);
     *              //如果不想此表格有编辑功能 pt.setEditable(false)
     *             
     *              //增加一行时:
     *                  var arrDa = new Array();
     *                  arrDa[0] = "VB";
     *                  arrDa[1] = "C#";
     *                  arrDa[2] = "数据四";
     *                  arrDa[3] = "PB";
     *                  arrDa[4] = "Java";
     *                  arrDa[5] = "2.112.521";
     *                  arrDa[6] = "中国";
     *                  pt.setCellData(arrDa); 
     *                 
     *              //然后调用add_row(mainTab)方法。
     *              //也可以不设置,增加一行,则自动填充每列的列数
     *
     *修改履历:
     *      2002.03.18  增加函数
     *              getColData(colIndex,isImg) //得到指定列的所有值,colIndex为列号,isImg指定此行是否为图片
     *              getRowData(rowIndex);//得到指定行的所有值,rowIndex为行号
     *
     *      2003.08.18 改变select的接口
     *              var arrText = new Array();
     *              arrText[0] = "数据一";
     *              arrText[1] = "数据二";
     *              arrText[2] = "数据三";
     *              arrText[3] = "数据四";
     *              var arrValue = new Array();
     *              arrValue[0] = "1";
     *              arrValue[1] = "2";
     *              arrValue[2] = "3";
     *              arrValue[3] = "4"; 
     *              pt.setCol(3,'sel',arrText,arrValue);
     *
     *              arrText为select的text,arrValue为select的value值
     *              注:构建表格时,必须select所在的所有td中指定data等于value值,例如:<td data="1">数据一</td>
     *    2003.07.18 修改addRow()方法
     *                      增加一条数据时,如果是select形式的编辑方式,则搜索sValue和sText
                            找到与输入值相符的value赋给td的data
