There was a question on the same issue about 2 years back and seems forgotten after that. I think this column resize (or at least wrap text if text is long) feature is still needed in the table viewer of rstudio. Or has it been developed?
Old post
I think it already has been developed
Did you try to resize columns in your Rstudio IDE ? Which version do you have ?
Resizing is IN and working now. Thanks guys.
