Hi All,
I'm looking for some help on column widths. I have a visualforce page in a record, as I would like to see 4 rows at once. 1 label and 3 fields. I would like the column widths to all be the same, but its all over the place. The first two columns are very large, and the last two squished at the end. Any help would be appreciated.
