好了上代码：

样式界面：

csharp 复制代码

    </div>
  </div>
</template>

js代码

csharp 复制代码

 // 增加一行
        addRow() {
      const row = {
        colcumn1: "",
        colcumn2: "",
        isEnable:"1",
      };
      this.tableData.push(row);
    },
    // 删除指定行
    delRow(index) {
      this.tableData.splice(index, 1);
    },
    // 指定位置插入行
    addRowIndex(index) {
      const row = {
        colcumn1: "",
        colcumn2: "",
        isEnable:"1",
      };
      this.tableData.splice(index + 1, 0, row);
    },

记得在 return 的data中定义数据 tableData: \[\],

完成！！
