Website: https://www.nldelphi.com/forumdisplay.php?43-NLDStringGrid
Features, compared to Delphi's default VCL TStringGrid:
Added functionality:
- Without settings, the component appears and acts exactly the same as the default TStringGrid
- Color properties can be set to the default color by setting to clDefault
- Merging of adjacent cells
- Inplace editor in style of current (merged) cell(s) which listens to F4
- Descends from TCustomDrawGrid
- Double clicking a column title autowidths the column
- CSV import/export
- Multiline text in (merged) cells
