el-table加上@select="handleSelection"
<el-table
  ref="Table"
  :data="apprItemData"
  :header-cell-style="headClass"
             @select="handleSelection"
             row-key="approveItem"
             :tree-props="{children: 'children'}"
             height="420"
  border>
</el-table>// 选择表格行
handleSelection (selection, row) {
  this.selectRows = row;
  this.selectTotal = selection.length;
  //console.log(row);
  //console.log(selection.length);
}
 然后在其它方法里,直接从this获取自己定义的vue对象拿就行
var rows = this.selectRows;
console.log("rows:"+rows);
 var size = this.selectTotal;
 console.log("size:" + size);
 if (size < 1) {
         top.dialog({title: '提示',content: "请选择至少一个选项!"}).show();
         return;
 }
var selItemName = rows.itemName;对表格数据进行遍历:
let approveItems ="";
 let itemArr = [];
 this.$refs.Table.selection.forEach(e => {
     itemArr.push(e.approveItem)
 })
 console.log("itemArr:" +itemArr);
 approveItems = itemArr.toString();
 console.log("approveItems:"+approveItems);
