How can I maintain the same row height when I have cells merged vertically

When I merge cells vertically while having a fixed height = 150,
what I expected was the cell after merge should have a height of 300, and the 2 rows on its right should have a height of 150 separately.

But instead of that now the cell after the merge has a height of 150, and the rows on its right became 75 each.

What did I miss here?

Hi @panjf1990

please take a look at https://github.com/handsontable/handsontable/issues/3837
There’s also a workaround that may help.
Let me know if it works for you as well.
