Fixed height of the first column in El table dynamic header rendering

Problem effect ： 

Don't talk much Go straight to the code

Key code ：

Add this after getting the data

 

The overall code ：

<el-table
        ref="stateStatisticsTable"
        :data="tableData"
        border
        style="width: 100%"
        :header-cell-style="{
          background: 'rgb(239, 248, 255)',
          color: 'rgb(96, 98, 102)',
        }"
        height="95%"
      >
        <template v-for="(itemData, indexData) in tableHeader">
          <el-table-column
            v-if="itemData.prop == 'unit'"
            :key="itemData.prop"
            :prop="itemData.prop"
            :label="itemData.label"
            :width="itemData.width ? itemData.width : '200'"
            align="center"
            fixed   // Fix the first column 
          >
          </el-table-column>
          <el-table-column
            v-if="itemData.prop != 'unit'"
            :key="itemData.prop"
            :prop="itemData.prop"
            :label="itemData.label"
            :width="itemData.width"
            align="center"
          >
            <template slot-scope="scope">
              <div
                style="width: 100%; display: flex; justify-content: center"
                v-if="scope.row[itemData.prop] == '1'"
              >
                <div
                  style="
                    width: 12px;
                    height: 12px;
                    background-color: #167cc7;
                    border-radius: 50%;
                  "
                ></div>
              </div>
              <div
                style="width: 100%; display: flex; justify-content: center"
                v-if="scope.row[itemData.prop] == '2'"
              >
                <div
                  style="

                ></div>
              </div>
            </template>
          </el-table-column>
        </template>
      </el-table>

          this.tableHeader = res.data.data.data[0].tableHeader; //  Back end returned header 
          this.tableData = res.data.data.data[1].tableBody;  //  data 
          this.$nextTick(() => {
            this.$refs.stateStatisticsTable.doLayout();  //  Important code 
          });
