Graphics, Figures & Tables ⇒ Table Cell Height and \arraystretch

[ChelseaBoot]

I have been trying to rescale the height of cells in a table:

but only the top half of the table seems to get adjusted and the bottom half cells tend to run into each other.

Any clues how to solve this?

Thanks

Please provide a minimal example that is compilable as provided for everybody.

Good that you posted a minimal example! So I could test it too. You will see that also the rows below will be adjusted if you raise the value of \arraystretch, set it for example to 2.5. Of course this is too much.

Btw. there are errors in the code: at the end of rows remove the & before \\.

You can extend the space between rows manually, write at the end of a row for example

Code: Select all

Ah, those "&"s are left over from a different table formatting. Thanks for pointing them out.

And the "[3ex]" works quite well. Thank you.

[localghost]

The booktabs package provides the \addlinespace command to insert additional space between lines. And by the way, to depict a transposed matrix you can simply use ^ \top.

Thanks for the reply localghost! "\addlinespace" is very useful.
