I am a beginner in Latex. I use Lyx to create tables and then I export the pdflatex script which I can simply paste in Overleaf. I am trying to create a table as follows.
As you can see the column width for column 4,5 and 8 is unnecessarily wide which takes my table almost to the edge of the page. I used nested table so that the column width decreases, but it seems it does nothing.
Here, is the pdflatex exported from Lyx.

I know I can manually set the column width in centimeters or inches. Isn't there an automated way to set the column width? I have multiple tables and I don't want to tinker them manually.
EDIT 1:
Here are the options in Lyx.

The problem is due to the preamble of the nested tabulars (for the column heads). You can replace each
{c}with{@{]c@{}}, or simpler, use themakecellpackage and its eponymous command. Furthermore, the table is too wide for the default text width, so I suggest loadinggeometry. Also, I loadedcaptionto have a more sensible spacing between the caption and the table.
