el-table的Checkbox多选框(选中、取消)

<el-table v-loading="itemLoading" ref="itemTable" 
	:data="itemTableData" 
	tooltip-effect="dark"
  	@select="itemHandleSelectionChange">
  <el-table-column type="selection" width="55"/>
  <el-table-column prop="id" label="ID" />
  <el-table-column prop="name" label="名称" />
</el-table>

在el-table上绑定@select=itemHandleSelectionChange事件,

methods方法:

itemHandleSelectionChange(selection, row) {
  console.log(selection);//获取所有已选中的数据
  console.log(row);//获取 选中/取消 的这一条数据,
  let selected = selection.length && selection.indexOf(row) !== -1
  console.log(selected)// true就是选中,0或者false是取消选中
},

设置只能选中不能取消

itemHandleSelectionChange(selection, row) {
  let selected = selection.length && selection.indexOf(row) !== -1
  // selected为false是取消选中操作
  if(!selected){
    //切换选中状态(从取消状态改为选中状态)
    this.$refs.itemTable.toggleRowSelection(row);
    console.log("取消不了!!!!")
  }
},
