【vue】使用el-table時，實現批量選中效果

簡單demo

①頁面：

<template>
  <el-table ref="multipleTable" :data="tableData3" tooltip-effect="light" style="width: 100%" @selection-change="handleSelectionChange" stripe border fit highlight-current-row>
    <el-table-column type="selection" width="55" :disable="isdisable">
    </el-table-column>
    <el-table-column label="日期" width="120">
      <template slot-scope="scope">{{ scope.row.date }}</template>
    </el-table-column>
    <el-table-column prop="name" label="姓名" width="120">
    </el-table-column>
    <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(tableData3)">全選</el-button>
    <el-button @click="toggleSelection()" :disabled="multipleSelection.length == 0">取消選擇</el-button>
  </div>
</template>

 ②交互：

export default {
    data() {
      return {
        tableData3: [{
          date: '2016-05-03',
          name: '王小虎',
          address: '上海市普陀區金沙江路 1518 弄'
        }, {
          date: '2016-05-02',
          name: '王小虎',
          address: '上海市普陀區金沙江路 1518 弄'
        }, {
          date: '2016-05-04',
          name: '王小虎',
          address: '上海市普陀區金沙江路 1518 弄'
        }, {
          date: '2016-05-01',
          name: '王小虎',
          address: '上海市普陀區金沙江路 1518 弄'
        }, {
          date: '2016-05-08',
          name: '王小虎',
          address: '上海市普陀區金沙江路 1518 弄'
        }, {
          date: '2016-05-06',
          name: '王小虎',
          address: '上海市普陀區金沙江路 1518 弄'
        }, {
          date: '2016-05-07',
          name: '王小虎',
          address: '上海市普陀區金沙江路 1518 弄'
        }],
        multipleSelection: [],
        isdisable:false,
      }
    },

    methods: {
    //全選,取消選擇
      toggleSelection(rows) {
        if (rows) {
          rows.forEach(row => {
            this.$refs.multipleTable.toggleRowSelection(row);
          });
        } else {
          this.$refs.multipleTable.clearSelection();
        }
      },
      handleSelectionChange(val) {
       //val 為選中數據的集合
        this.multipleSelection = val;
      }
    }
  }
