[Tex/LaTex] Beamer Table Alignment

Question

I am wondering how to delete the empty space on the right side of the last column. Also, is there any way to align Panel A and B in beamer?

Answer 1

I would redesign your table as follows:

• reordered code in editor such that, already in it, the code mimics the table structure. With this it is simpler to discover all missing parts of code
• merge both tables in one
• remove superfluous rules
• use only rules defined in package booktabs
• make your mwe works
  1. remove \tikzmark stuff (seems to be wrongly used)
  2. instead frame around rows use \rowcolor
  3. remove superfluous packages in preamble (like colorab, xcolor; both are loaded by beamer using option table ...)
• replace unknown column type Y with S defined in package siunitx
• in mwe consider only relevant packages and frame

this effort resulted with:

After that result in case that the rectangles around now colored rows are required for some reason, i would investigate how to properly use tikzmark for drawing them.

I guess that frames around rows should be as show next image. for it some changes to above mwe are done. indicated are with % <---:

To obtain above image of table the mwe had to be compiled at least twice.
