I have a usage of handson table where there are 20*300 cells. When setting viewportColumnRenderingOffset to 300 (to improve the scrolling lag), the scrolling seems to fine, but the cell editing is very slow. It takes almost 15 secs, to edit a cell. This is because, I noticed that afterCellSetMetaData gets called individually for each of the cell even when one of the cell is edited.
Please can you suggest what I’m missing here or is this some performance bug from your side.
