I often have tables with many columns (ranging 30-50). Usually in these cases the columns come in “families” - What I mean by this is often times I have 2-3 columns that are related or all working in tandem to support one main column that is displayed (usually to break up formulas to not have extremely lengthy/expensive filter() formulas)
I try to sort this visually with some tag at the end of the column name, but this gets difficult and im not as on top of it as i should be. When I have to go fix a formula or look into a certain aspect of how the doc is working (especially if its been a while since I was working on the document) it takes me forever to hide/unhide columns and figure out which ones are dependent on and working in tandem with others.
I would LOVE if we could add some organization to the columns, potentially put them in folders, or add #hashtags to them to group them in families? That would be soooo helpful and save so much time especially when returning to a document after a long time trying to remember how it all fits together.
