Show name of column in tooltip?

[iskandr]

When I scroll past the first page of variants, it's hard to tell which column all the numeric values correspond to (e.g. [1, 1] [42, 42] 43 0 [0, 0] 0 0). One way to clarify this is to add the column name to the tooltip that pops up on hover.

We could also stick the header, like how it works on a spreadsheet.

:+1: sticky header. The first thing I do with every Google Spreadsheet is to pull that thing on the left down so that the first row becomes a sticky header row.

Yeah it would be great to have a sticky header. Will need to do some research to see how we can make that play nicely with a table.
