I can see what you mean. It happens only when we set some height to the table. I do not know if it’s a proper workaround for your project but maybe you can add a parent element with fixed width instead of adding it to Handsontable. It’s a hack however it’s more than nothing until we fix the issue.
We are planning to change the whole structure of building fixed rows/columns and minSpareRows/cols but we’re still testing it.
Yep, we need to define a height for the table because it is fixed to the bottom, then when the user resizes the windows, we update the height. For now, we solved it hidden the fixed-row. Thanks for your answer
