在使用ElementUI，需要ElementUI表格table组件实现单选及禁用默认选中效果,
先看下效果图：

代码如下：

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

<script>
  export default {
    data() {
      return {
	    selected:'',//选中的名字
        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: {
      //点击行
	 rowClick(row, column, event)
	 {
	     this.$refs.multipleTable.toggleRowSelection(row);
	 },
	 //改变时
	 handleSelectionChange(val)
	 {
	     if (val.length > 1)
	     {
	         this.$refs.multipleTable.clearSelection()
	         this.$refs.multipleTable.toggleRowSelection(val.pop())
	         console.log("handleSelectionChange1:",val)
	     }
	     else
	     {
	         if(val.length==1)
	         this.selected = val[0].name
	     }
	     if(val.length==0)
         this.selected = '';
	 }
 
    }
  }
</script>
