Table: Applying colors to diagonal cells

[AbdealiLoKo]

We were using the Table trace type and we wanted to try giving the diagonal cells a color so it was easy to distinguish them and see data on either sides. (I think that is a common usecase to show matrices and so on)

I looked at the documentation and saw that the fill attribute in cells but it only supports an array i.e. a specific color can be applied to a column.
Was wondering how I could achieve this using plotly tables ? Cell level color fills

Thanks for writing in!

This should be possible using cells.fill.color.

See https://codepen.io/etpinard/pen/bzVENX?editors=1010, is that what you're looking for?

@etpinard Thanks a lot. That is what I need.

I did not realize I could provide a 2D array in that and did not try :/
Should I close the issue or keep it for documentation improvement maybe ?

Currently it says:

Sets the cell fill color. It accepts either a specific color or an array of colors.

That will be done in #3481

Thanks again for the report!
