Feature: Drag columns and rows

[dg-ac]

We can already select full columns and rows, so ideally the next step should be to also allow reordering columns and rows by dragging them.

Right now, when only a cell is selected, column and row header should use a grey-200 background.

When the full column and row header is selected, the background should use a grey-400.

When full columns/rows are selected, hovering over these headers should change the cursor to cursor: grab.

User should be able to drag columns right and left, and rows up and down.
While dragging, we’ll show:


• a 2px grey-400 divider in the same spot where the dragged column will land
• an overlay with the same width as the column we want to move. Should use a grey-400 background with 28% opacity

This is a good idea, perhaps a first step will be to have ("Move to right/left" in the context menu).

I have a question though, how often people would use something like this?

[dg-ac]

Hard to answer that. It's something that I use but doesn't need to be necessarily common. In any case, we can give it a low priority and focus on other features for now.
