Do not render all columns in md table mode?

[azazellochg]

Transferred from scipion-em/scipion-em-relion#19:

When open set of 2d classes and display particles from a certain class in table mode, the default table looks a bit of overkill, also making it slow to render. There are 60 columns!!!!

I am thinking maybe we should not display the following columns by default, a lot of them are empty of duplicating the other ones:

• label (empty)
• comment (empty)
• coordinate.micId (micid is enough?)
• ctfmodel.micobj.index
• ctfmodel.micobj.filename (this causes very slow rendering)
• ctfmodel.micobj.index
• ctfmodel.micobj.micname (same as coordinate.micname in most cases)
• ctfmodel.micobj.plotglobal.index
• ctfmodel.micobj.plotglobal.samplingrate
• ctfmodel.micobj.psdjpeg.index
• ctfmodel.micobj.psdjpeg.filename (this causes very slow rendering, it's same thing
  as ctfmodel.micobj.filename)
• ctfmodel.micobj.psdjpeg.samplingrate
• ctfmodel.micobj.thumbnail.index
• ctfmodel.micobj.thumbnail.filename
• ctfmodel.micobj.thumbnail.samplingrate

Thoughts? @pconesa

I agree, it seems too much.

Just 2 comments:
1.- Not sure if hiding them will increase performance, but in any case is worth trying and at leass not overwhelm users with all those fields.
2.- This one might be tricky to resolve. Since the particles "view" is triggered from java itself if I'm right with the default behaviour (show everything). The decision, I guess should come from python, and that communication is not established.

We need to think how to provide that control to python code, or come up with a "general/common list of fields to hide/or show.

Thanks, @azazellochg.
