I don't think that's even possible in Calc, apart from using autoformats or conditional formatting (various questions about it on Ask), but couldn't find a corresponding enhancement request.

Slightly related to enhancement requested in bug 33201.

UX team, thoughts about a UI option for that?

Dark vs. Bright appearance

The enhancement request is to have alternate shading for the table rows. The issue seems to me rather related to the strong color contrast since we draw the table lines in pure white. Would it be an advantage if the grid is drawn in light grey?

No.

It might be slightly easier on the eyes, but the host theme colours should determine that, I imagine. Since it wouldn't solve this issue for me, I'd decide how to implement lighter line colours (if desirable) in another issue.

Thanks, anyway.

Although, per https://bugs.documentfoundation.org/attachment.cgi?id=187079, it does seem like the dark theme is fairly inconsistent with the light one, and I do think that the lower contrast is nicer on the eyes.

I'd love to see a new bug about this if you're willing, so that I can subscribe to it.

We maybe do not read the colors correctly on every OS. Please file a new bug 

Let's discuss the alternating row color here. I think it's too much visual noise.

Off-topic: Mind to shorten your alias?

Dialog with grid control shows how alternating colors will work

Alternating colors for rows will work in a dialog by default.

At this moment it is impossible to set this alternating colors for a grid control in a form. There is no property available to get this by macro.

Working directly with tables, not in a form, has same problems.

You will need this alternating of colors for tables with many fields. So you could better see: I have changed only this row and hadn't erroneously changed another.

An option to set alternating colours or shadings, as is possible for tables in dialogs or in Writer, would indeed be helpful in some cases.

Obviously a highly welcome option, let's do it.
