Thank You HN. This is the first time, i've read about a working free JS DataGrid. Until now, I had to build those in ActionScript. It'd be nice to drop Flash from my projects.

Has anyone gathered some experience with both (JS + Flash DataGrids) and could tell me how they differ in performance (average load time, memory usage), compatibility (like browser-versions) and stability ?

(Most interestingly: Huge loads of Data. Flash gets slow, but doesn't crash. Google Spreadsheet for example, does)
