Is it possible to control the border thickness of the tables in LyX? In the LyX documentation it written:
\arrayrulewidthis the thickness of the cell border line, the default is
But I don't seem to understand how to user
\arrayrulewidth. not really familiar with LaTeX. Is it possible to increase the thickness of the borders (make the more bold) in LyX? Also, I read some previous threads but they all solved the problem with LaTeX and not with LyX.
