Summary by Sourcery

Optimize table column visibility logic by replacing repeated Find calls with precomputed name lists and using Contains for faster lookups.

Enhancements:

• Use a list of visible column names and Contains in GetVisibleColumns to filter columns
• Use a distinct list of visible column names and Contains in GetColumnsListState to determine column list state

Hey there - I've reviewed your changes - here's some feedback:

• Consider using a HashSet for the projected visible column names to get O(1) lookups and avoid repeated list allocations.
• Right now GetColumnsListState rebuilds the visible names list on every call—extracting that projection into a shared helper or caching it would reduce redundant enumeration.
