I'm interested in good practice for table (
figure layout, especially in good references. What do typographers have to say about this. Please provide references if you can.
To focus the question, I'd like to ignore (La)TeX solutions to implementing a table layout because if we have 10
figure designs and five packages for implementing tables/figures, we may end up with 50 different solutions and we won't be able to see the wood from the trees.
I'm particularly interested in guidelines/good practice for aligning data in table rows, columns, and row and column headers. Finally, I'm interested in ideas that can be used to let
figure blend in with the rest of the text, without interrupting the rhythm of the main text.
I'm aware this group is about TeX and LaTeX and some may consider the question inappropriate because it doesn't ask for specific (La)TeX solutions. Still I think the question has its merits because the answers to the questions should be known by anybody trying to implement a table.
