Borders around the spreadsheet title in Claris Resolve can be added or removed fairly easily by typing commands into the entry bar:
To Add a Title Border:
1. Type Select Report Header in the entry bar & then hit Command-Return which executes this script command immediately
2. Then type Single Line Border & again hit Command-Return
Some other options that are available are Double Line Border and No Line Border (to remove a border).
More information can be found in the on-line Claris Resolve Script Reference under the heading Select [More] Report Header.
