DataTable: Rowspan not working correctly when returning it from passThrough bodyCell (of Column)

[ahkiva]

Describe the bug

If bodyCell pt function returns rowspan ({rowspan: '2'}) in DataTable component then it does not work, but it works when rowSpan is in camelCase (colspan works correctly). I guess rowspan (all lowercase) should work also.

Steps to reproduce the behavior

In DataTable component, add bodyCell pt function to Column and let the function return {rowspan: '2'} then it will not work (only works if using {rowSpan: '2'}).

Expected behavior

Lowercase letters should also work rowspan (it works for colspan).
