[Tex/LaTex] How to create a compact comparison table like this

tables

How do you create a comparison table like this?

enter image description here

In particular, the slanted labels that save space, and the circles / half-filled circles. These kinds of tables seem fairly common — is there a special package for creating tables like this?

Also, I think there already is a question about exactly the same kind of table, but unfortunately it had a title as vague as this one, so I wasn't able to find it.

Here's a partial reconstruction of the table.

\documentclass{article}
\usepackage{amsmath}
\usepackage{array}
\usepackage{booktabs}
\usepackage{fullpage}
\usepackage{graphicx}
\usepackage{threeparttable}
\usepackage{wasysym}

\begin{document}
\begin{table}
\footnotesize
\newcommand*\rot[1]{\hbox to1em{\hss\rotatebox[origin=br]{-60}{#1}}}
\newcommand*\feature[1]{\ifcase#1 -\or\LEFTcircle\or\CIRCLE\fi}
\newcommand*\f[3]{\feature#1&\feature#2&\feature#3}
\makeatletter
\newcommand*\ex[9]{#1\tnote{#2}&#3&%
    \f#4&\f#5&\f#6&\f#7&\f#8&\f#9&\expandafter\f\@firstofone

\makeatother

Some comments.

  1. I defined \rot to handle rotating the slanted labels. It uses \rotatebox[origin=br]{-60} to rotate the label -60 degrees about the bottom right corner. That is placed inside an \hbox that's 1em wide with infinite shrinkability on the left so that the label protrudes out the left side of the box.
  2. I didn't want to type \LEFTcircle and \CIRCLE from the wasysym package over and over, so I defined \feature which takes a single argument (in this case, 0, 1, or 2) and produces the appropriate symbol. (Based on the footnotes, I probably should have called it \property instead.)
  3. The main part of the table is grouped into groups of 3 which are themselves grouped into 2 or 3 groups of 3. Using the array package, I created a new column type G (for group) that corresponds to three centered columns with no intercolumn space. I also defined \f which takes three digits and produces the three features (properties) for a group. (I probably should have gone with \g to stick with group rather than \f for features.)
  4. To get extra space between the groups of groups, I used the array specifier ! to insert an extra \kern1em between those columns.
  5. Each row logically consists of 10 parts: the scheme, the table note symbols, the example, and seven groups of 3. TeX only supports macros with up to 9 arguments, so when I created \ex (which was to stand for example, but on reflection, something related to scheme would have been better) which takes 9 arguments. The first 3 correspond to the scheme, marks, and example. The remaining 6 expect 3 digits to pass to \f. Finally, the 10th braced group is unbraced using \@firstofone and then passed to \f. I admit, that's kind of a hack, but it makes using \ex easier.
  6. threeparttable consists of a caption, the tabular, and the tablenotes below.
  7. The tabular itself is pretty straight-forward. I've used booktabs's \toprule, \midrule, and \bottomrule to typeset the horizontal rules. (This looks much better than \hline.)
  8. The table notes are centered in your example. I had to work a little bit to get that here. In particular, I added some \hfils. I think it would look better to not center the notes.
  9. Scheme is indented slightly for some reason in your example. I didn't understand the point of that, so I didn't do it. Adding \quad (or some other horizontal spacing command) could reproduce that.
  10. If I were creating this table, I would typeset the "Example" column left-aligned. I might also replace the - in that column with None or maybe just leave it blank. I'd probably also replace the - in the main columns with an en dash. I just think it looks better. Conveniently, you only have to replace - with -- in \feature to change it everywhere, including the table notes.

Some metacomments.

  1. To find individual symbols, you should look in the symbols-a4 document (run texdoc symbols-a4).
  2. Generally speaking, asking TeX SX to reproduce some particular image doesn't work out too well. (I was just curious to learn about threeparttable which I'd never used before so I took a stab at it.) Posting a minimal example demonstrating what you've tried and asking about particular elements you are stuck on works best. E.g., "How do I rotate the text in a cell of a table?"
