Pinning first row of file

[Dani21]

When comparing files in table mode, I'm requesting a feature that can be turned on where instead of showing A, B, C, etc as the text of the pinned/frozen/hovering row, the first row can be the first row of data so that it always shows (ie. column headers). This could be an option named "Freeze first N rows" and "Freeze first N columns" if you want to be the most flexible, or to keep it simple "Always show data header line". I would've used this feature today if it was available or I could find it (ie. I'm not just thinking of ideas and posting them here).

Slightly different from your request, but I have added the ability to display the first line as headers.
