Making latex multicolumn width wider in Rmarkdown

I want to make my LaTeX table (picture below) in Rmarkdown to the full width(so that it fits the caption), which requires the 2ndto 5th columns to be extended. I went through multiple links(one,two) but failed. How can I make the table to the full width, and if the columns 2- have the same width, it would be better. enter image description here

Here is the code

Solution

  • As said before, I would use the tabularray package. This will give a much nicer result. No white gaps between cells, better spacing ...
