Is there a possibility to set the first column width to extend based on the keyword names? In this case the "Web Browser" text extends into the 0-1 period. I would like to have t=0 where the "Web Browser" text ends to prevent it to overlap my highlight name.
Also, is it possible to extend a period with to fit the highlight name? Here "45" extends into period the 1-2
