el-table删除选中的多行(无视id重复)

• el-table设置一个row-class-name来协助获取index

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

• 给el-table的row附上index的值

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

• 把获得的下标放到selectionItemIndexes里

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

• 触发删除的函数

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