效果預覽

實現原理

通過改css樣式實現

1. 去掉第一個單元格的下邊框
2. 第一列第一個單元格和第二個單元格的偽元素設定絕對定位，寬度設成1px,高度根據自己表格調整
3. 通過旋轉兩個單元格偽元素，並設定旋轉起始點，使兩個偽元素旋轉到重合位置，達到斜線的效果

HTML

          border
          resizable
          show-overflow
          :data="tableData"

          :edit-config="{trigger: 'click', mode: 'cell'}"

            <vxe-colgroup field="group0" title="投產類別" align="right">
