What it means
Rows config is for exceptions to the normal row rhythm, such as summary rows, banners, or records that need a little more room than the rest.
Structure guide
Rows Config data grid documentation
Rows config is for exceptions to the default row rhythm. Use `rowsConfig.rowHeights` when only a few records need more space than the baseline `layout.rowHeight`.
When to use it
Use it when only a few rows need different treatment instead of changing the height of the whole grid. It is especially useful for grouped summaries, exception rows, and detail-heavy records that need more space.
Implementation notes
Keep row-specific treatment for true exceptions. If every row needs it, move that choice back into the base layout. Use stable row ids when assigning row-level sizing or styling so the same records keep the same treatment across refreshes.
