@DR-Univer @lumixraku cc 数据应该是对的 应该是边框线的渲染规则不太一致

@DR-Univer @lumixraku cc The data should be correct. It should be that the rendering rules of the border lines are not consistent.

There is also this operation scenario, and the rendering results are not as expected.

[lumixraku]

Consistent with Google Sheets, but different from Excel. It is designed this way.

[waterhydroxyl]

If I perform the same operation in Google Sheets, the border lines do not change in any way. However, the expected scenario is to match Excel. I tried Tencent Docs, and it also allows clearing some border lines of merged cells.
