• el-table設(shè)置一個row-class-name來協(xié)助獲取index

<el-table :data="tableData"
             :row-class-name="tableRowClassName"
             tooltip-effect="light"
             style="width: 100

• 給el-table的row附上index的值

 tableRowClassName(row, index) {
        row.row.index = row.rowIndex;
      }

• 把獲得的下標(biāo)放到selectionItemIndexes里

 handleSelectionChange(rows) {
        this.selectionItemIndexes = [];
        rows.forEach(item => {
          this.selectionItemIndexes.push(item.index);
        });
      },

• 觸發(fā)刪除的函數(shù)

deleteData() {
        this.tableData = this.tableData.filter((item, index) => {
          let arrlist = this.selectionItemIndexes;
          return !arrlist.includes(index);
        });
      }
