官方文档借鉴：

 

 

 

<template>
  <el-table
    ref="multipleTable"
    :data="tableData"
    tooltip-effect="dark"
    style="width: 100%"
    @selection-change="handleSelectionChange">
    <el-table-column
      type="selection"
      width="55">
    </el-table-column>
    <el-table-column
      label="日期"
      width="120">

    </el-table-column>
    <el-table-column
      prop="name"
      label="姓名"
      width="120">

    <el-table-column
      prop="address"
      label="地址"
      show-overflow-tooltip>
    </el-table-column>
  </el-table>
  <div style="margin-top: 20px">
    <el-button @click="toggleSelection([tableData[1], tableData[2]])">切换第二、第三行的选中状态</el-button>
    <el-button @click="toggleSelection()">取消选择</el-button>
  </div>
</template>

<script>
  export default {
    data() {
      return {
        tableData: [{
          date: '2016-05-03',
          name: '王小虎',
          address: '上海市普陀区金沙江路 1518 弄'
        }, {
          date: '2016-05-02',
          name: '王小虎',
          address: '上海市普陀区金沙江路 1518 弄'
        }, {
          date: '2016-05-04',
          name: '王小虎',
          address: '上海市普陀区金沙江路 1518 弄'
        }, {
          date: '2016-05-01',
          name: '王小虎',
          address: '上海市普陀区金沙江路 1518 弄'
        }, {
          date: '2016-05-08',
          name: '王小虎',
          address: '上海市普陀区金沙江路 1518 弄'
        }, {
          date: '2016-05-06',
          name: '王小虎',
          address: '上海市普陀区金沙江路 1518 弄'
        }, {
          date: '2016-05-07',
          name: '王小虎',
          address: '上海市普陀区金沙江路 1518 弄'
        }],
        multipleSelection: []
      }
    },

    methods: {
      toggleSelection(rows) {
        if (rows) {
          rows.forEach(row => {
            this.$refs.multipleTable.toggleRowSelection(row);
          });
        } else {
          this.$refs.multipleTable.clearSelection();
        }
      },
      handleSelectionChange(val) {
        this.multipleSelection = val;
      }
    }
  }
</script>

 那么我们参考官方文档之后，如果进行行选中要用到@row-click

代码如下：

 

 @row-click="toggleSelection"
      ref="multipleTable"

 然后在

 data() {

    return{

//点击数据选中或取消

      multipleSelection: [],

}

}

 

methods里代码如下：

 //点击当前行数据进行选中或取消复选框
    toggleSelection(row) {
      //通过ref绑定后这里使用$refs.table来操作bom元素
      this.$refs.multipleTable.toggleRowSelection(row);

    },

 然后效果便可实现

点击某行数据，便可选中或者取消某行数据
