• el-table展开行修改


    直接进入正题,官网上el-table的展开行样式如下:

    我不想显示前面的展开符号,并且想增加一个按钮,点击就可以展开和关闭,

    想到一个办法,首先让展开符号那一列不显示,然后在新增一个按钮绑定一个点击方法,开控制其展开和关闭。

    1、将扩展符号列隐藏掉

    第一步:将扩展列的宽度置为0,黑色加粗并带有下划线处

    <el-table
        :data="tableData"
        style=" 100%">
        <el-table-column type="expand" width="0">
          <template slot-scope="props">
            <el-form label-position="left" inline class="demo-table-expand">
              <el-form-item label="商品名称">
                <span>{{ props.row.name }}</span>
              </el-form-item>
              <el-form-item label="所属店铺">
                <span>{{ props.row.shop }}</span>
              </el-form-item>
              <el-form-item label="商品 ID">
                <span>{{ props.row.id }}</span>
              </el-form-item>
              <el-form-item label="店铺 ID">
                <span>{{ props.row.shopId }}</span>
              </el-form-item>
              <el-form-item label="商品分类">
                <span>{{ props.row.category }}</span>
              </el-form-item>
              <el-form-item label="店铺地址">
                <span>{{ props.row.address }}</span>
              </el-form-item>
              <el-form-item label="商品描述">
                <span>{{ props.row.desc }}</span>
              </el-form-item>
            </el-form>
          </template>
        </el-table-column>
        <el-table-column
          label="商品 ID"
          prop="id">
        </el-table-column>
        <el-table-column
          label="商品名称"
          prop="name">
        </el-table-column>
        <el-table-column
          label="描述"
          prop="desc">
        </el-table-column>
      </el-table>

    修改完效果如下:

    发现扩展符号还在,这时就要修改CSS属性了,将其隐藏

    第二步:修改CSS将扩展符号隐藏

      .demo-table-expand {
        font-size: 0;
      }
      .demo-table-expand label {
        width: 90px;
        color: #99a9bf;
      }
      .demo-table-expand .el-form-item {
        margin-right: 0;
        margin-bottom: 0;
        width: 50%;
      }
      /*此处为新增CSS,在vue中使用要加/deep/*/
      /deep/ .el-table__expand-icon{
        visibility: hidden;
      }

    此时效果如下:

    2、新增按钮,并添加方法,点击展开或关闭

    在table上新增属性,并新增一列用于展示展开按钮,注意斜体下划线处。

    <el-table
          :data="tableData"row-key="id":expand-row-keys="expands"
          style=" 100%">
          <el-table-column type="expand" width="0">
            <template slot-scope="props">
              <el-form label-position="left" inline class="demo-table-expand">
                <el-form-item label="商品名称">
                  <span>{{ props.row.name }}</span>
                </el-form-item>
                <el-form-item label="所属店铺">
                  <span>{{ props.row.shop }}</span>
                </el-form-item>
                <el-form-item label="商品 ID">
                  <span>{{ props.row.id }}</span>
                </el-form-item>
                <el-form-item label="店铺 ID">
                  <span>{{ props.row.shopId }}</span>
                </el-form-item>
                <el-form-item label="商品分类">
                  <span>{{ props.row.category }}</span>
                </el-form-item>
                <el-form-item label="店铺地址">
                  <span>{{ props.row.address }}</span>
                </el-form-item>
                <el-form-item label="商品描述">
                  <span>{{ props.row.desc }}</span>
                </el-form-item>
              </el-form>
            </template>
          </el-table-column>
          <el-table-column
            label="商品 ID"
            prop="id">
          </el-table-column>
          <el-table-column
            label="商品名称"
            prop="name">
          </el-table-column>
          <el-table-column
            label="描述"
            prop="desc">
          </el-table-column>
          <el-table-column label="操作" align="center">
            <template slot-scope="scope">
              <el-button size="mini" @click="expandRow(scope.row)">展开</el-button>
            </template>
          </el-table-column>
        </el-table>

    然后新增一个expandRow()方法

    expandRow(row){
        if (this.expands.indexOf(row.id) < 0) {
            this.expands = [];
            this.expands.push(row.id);
        } else {
            this.expands = [];
        }
    },

    并在data中新增一个expands数组变量

    data() {
        return {
            tableData: [{
                id: '12987122',
                name: '好滋好味鸡蛋仔',
                category: '江浙小吃、小吃零食',
                desc: '荷兰优质淡奶,奶香浓而不腻',
                address: '上海市普陀区真北路',
                shop: '王小虎夫妻店',
                shopId: '10333'
            }, {
                id: '12987123',
                name: '好滋好味鸡蛋仔',
                category: '江浙小吃、小吃零食',
                desc: '荷兰优质淡奶,奶香浓而不腻',
                address: '上海市普陀区真北路',
                shop: '王小虎夫妻店',
                shopId: '10333'
            }, {
                id: '12987125',
                name: '好滋好味鸡蛋仔',
                category: '江浙小吃、小吃零食',
                desc: '荷兰优质淡奶,奶香浓而不腻',
                address: '上海市普陀区真北路',
                shop: '王小虎夫妻店',
                shopId: '10333'
            }, {
                id: '12987126',
                name: '好滋好味鸡蛋仔',
                category: '江浙小吃、小吃零食',
                desc: '荷兰优质淡奶,奶香浓而不腻',
                address: '上海市普陀区真北路',
                shop: '王小虎夫妻店',
                shopId: '10333'
            }],
            expands:[],
        }
    },

    整个Vue组件代码如下:

      <div>
        <el-table
          :data="tableData"
          row-key="id"

          style=" 100%">
          <el-table-column type="expand" width="0">
