In a paper, I'm using a large amount of associative tables. Tables with a key and value. Since both the keys and values are quite short, this is quite space inefficient.
One could repeat the column headers and thus make more use of a row. For example
H1 H2 A 1 B 2 C 3 D 4
H1 H2 H1 H2 A 1 C 3 B 2 D 4
Is their a package to handle such transformations automatically. Doing this manually is quite cumbersome (because the tables are generated by programs) and if it is not always straight forward how much repeats fit on one page...
