# [Tex/LaTex] baselinestretch vs. setspace

line-spacing

In my preamble I use \renewcommand{\baselinestretch}{1.5} to get "onehalf" line spacing. This works fine.

Then I started to use tnote in a threeparttable.

I changed font size to \scriptsize as I think it is big enough for the table notes. I discovered that the line spacing on the \tnote \items is to big. I found an advice in the LaTeX wikibook that line spacing in lists can be changed using \itemsep1pt \parskip0pt \parsep0pt.

Unfortunately this only works when using the setspace package. But activating this package has an impact on all table/tabular environments in that all cells have a smaller padding.

How can I avoid this impact on tables or is there another possibility to change line spacing in lists, e.g. the tnote list in a threeparttable?

If you want to adjust the spacing of text you should avoid to change the \baselinestretch as it changes the spacing for everything in the document, including footnotes and tables, which is usually not desirable (of course, if you want that effect then \renewcommand{\baselinestretch}{1.5} is correct)

If you want a typographically pleasing result rely on the setspace package as this changes only the spacing of body text and the bibliography. As Paul Stanley noted, setting the document to \onehalfspace is less than a baselinestretch of 1.5. If you want the same effect use \setstretch{1.5}.

Now, with regards to your table there are several ways. First, do not use the center environment, but instead \centering. Second, you have specified way to many columns - your table only has two. If you a table with the same look and feel as your current one, the easiest way is to use \renewcommand{\arraystretch}{1.2} which adds space above and below each row. This document might be useful to you.

If you want an aesthetically pleasing table use the booktabs package and avoid vertical rules and horizontal rules apart from one each at the top, bottom and the head. If you do that, then \setlength{\extrarowheight}{3pt} is the best way to increase spacing and the table will look much nicer overall. The MWE below should clarify things:
