Bulk search doesn't render table correctly

[sacdallago]

When adding proteins to to the search (after an initial rendering) the table doesn't seem to render all headers correctly:

Might be ahead of time (e.g. the feature is not finished), but reporting just in case.

UPDATE: I seem to understand why you did this (no experiments = no need for header). But then I'd rather have a separate UI element that collects all proteins with no hits.

Also: too many proteins will overflow table, and it won't scroll:

@KlausNie with the new table, there still is a visualization issue (e.g. visualizing one protein across multiple experiments:).

fix testable in branch unstable.

also reworked the coloring, which should now always match (if a cell is not contained/contained/selected)
