Should table format follow text format in submitted manuscript when no format specified? I am currently writting my first manuscript and there is no specifications about tables format in the author guidelines of the journal. If I follow the text format (double spaced, Times New Roman 12 pts) some of my tables which are very extensive will look awfull.

Should I modify their structure so they look better (but only in the manuscript) or should I keep my own format?
If you can't wait for a reply from the editor which is probably the best solution, then check out some of the articles that journal has already published and see how the tables were formatted.

You will recognise single spaced, double spaced etc...
