         format="yyyy-MM-dd"
         value-format="yyyy-MM-dd"
         placeholder="购买日期">

     </el-table-column>
     <el-table-column prop="bookbuytime" label="购买日期">

         icon="el-icon-delete"
         @click="handleDelete(scope.$index, scope.row)">删除
        </el-button>
       </template>

 </div>
</template>

vuejs 代码

export default {
  name:'TestWorld',
  data() {
    return {
      tableData:[{
        bookname: '',
        bookbuytime: '',
        bookbuyer: '',
        bookborrower: '',
        bookvolume:''
      }]
    }
  },
  methods:{
    addLine(){ //添加行数
      var newValue = {
         bookname: '',
         bookbuytime: '',
         bookbuyer: '',
         bookborrower: '',
         bookvolume:''
       };
      //添加新的行数
      this.tableData.push(newValue);
    },
    handleDelete(index){ //删除行数
      this.tableData.splice(index, 1)
    },
    save(){
     //这部分应该是保存提交你添加的内容
     console.log(JSON.stringify(this.tableData))
    }
  }
 
}

3.批量删除行数

<template>
  <div class="TestWorld">
    <el-table ref="multipleTable" :data="tableData3" 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">
        <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="batchDelete">批量删除</el-button>
     <el-button @click="toggleSelection()">取消选择</el-button>
   </div>
  </div>
</template>
 

vuejs 代码

export default {
  name:'TestWorld',
  data() {
    return {
        tableData3: [
          {
           date: '2016-05-03',

          }],
          multipleSelection: []
    }
  },
  methods:{
    toggleSelection(rows) {
      if (rows) {
        rows.forEach(row => {
        this.$refs.multipleTable.toggleRowSelection(row);
      });
      } else {
        this.$refs.multipleTable.clearSelection();
      }
     },
     batchDelete(){
       let multData = this.multipleSelection;
       let tableData =this.tableData3;
       let multDataLen = multData.length;
       let tableDataLen = tableData.length;
       for(let i = 0; i < multDataLen ;i++){ 
         for(let y=0;y < tableDataLen;y++){
           if(JSON.stringify(tableData[y]) == JSON.stringify(multData[i])){ //判断是否相等，相等就删除
            this.tableData3.splice(y,1)
            console.log("aa")
           }
         }
       }
     },
     handleSelectionChange(val) {
      this.multipleSelection = val;
     }
  }
