I have found a couple of solutions how to align row of numbers in table environments for example here and here. From a philosophical point of view can I use these solutions with proportional fonts ? Or is there requirement to use monospaced (typewriter) font ? I know theoretically there is no problem with this but I am curious if Latex can handle this. From the point of view of readibility monospaced font is better because when decimal points are aligned, then also other digits are nicely aligned and the reader can quickly compare numerical values in different rows.
I thought of using old style figures for numerical values in my tables (for example by using
\oldstyleenums switch). Have all old style figures the same width or every digit has different width? My document is written in
tgpagella font (because of good support for Czech & Slovak language glyphs).
