Table: Don't wrap text labels for gauge cells

[codeincarnate]

This is a potential fix for a support issue with the bar gauge in the table panel in which labels will wrap at lower cell widths.

Special notes for your reviewer:

Please check that:

• It works as expected from a user's perspective.
• If this is a pre-GA feature, it is behind a feature toggle.
• The docs are updated, and if this is a notable improvement, it's added to our What's New doc.
