The rows pane on the left can only show two attributes tiles at once. When creating a table chart which may contains many more attributes than just two, It is super tedious to navigate and re-order attributes.
If it is not possible to implement resizing the Rows pane, at the very least we should be able to drag an attribute tile upwards and downwards, and the attribute list should automatically scroll accordingly. Currently, this doesn't happen. So the only possible workflow is to drag a tile upward one slot at a time from the bottom. Can you imagine having to do this on a table containing 10 columns?
