The columns for the regular "Table" reports will auto adjust to the size of the screen that the user is on, so it is not possible to set the column width. Typically if there are a lot of columns it will wrap the text as much as it can to fit all the columns on the report without causing side to side scrolling.
The minimum width for wrapping will be determined by the shortest word in the text or the shortest word in the column heading.
If you have a particular problem and can post a screen shot, .I may be able to offer some other tricks.
