Is it possible to add two spaces after the number in the TOC?

The default appears to be one, but I need two.

Example:
2.3. Process Domain

Which is one space after the 2.3.

How to get two?

Thru my testing it doesn't seem to have anything to do with the number of spaces in the body of the Word doc.

Any thoughts?

This is likely not a space, but a tab. If so it is easy to fix by changing the TOC styles to move the tab setting.

Thanks Charles. I used a non-printing format and all seems to be well.
