Last change on this file since b2be4c19a1 was 0a4e16b182, checked in by Oleksii Serdiuk, 13 years ago

Added a border to tables in the solution output. Looks more readable
with long numbers, now. The border color can be controlled through
Output/Colors/TableBorder? setting in tspsg.ini. It is in #RRGGBB format.
