I've read through some questions re: longtable and how to make it fit the width of the page but have been unsuccessful. In the example, the table fits the width of the page but goes outside of the specified margins. MWE attached. Thank you!

I think the table would look much better if you (a) were to use 'raggedright` instead of centered alignment and (b) used single-spacing. In addition, do examine the correctness of your claim that "the table fits the width of the page". In my calculations (shown in the code below), the widths of the columns must be strictly less than 8cm.

Oh, and do note that longtable environments are automatically centered -- no need to encase them in center environments.

  • To vertically center the material in both columns, simply switch from p{\mylen} to m{\mylen} in the setup of the longtable. Speaking for myself, though, I think that top-alignment is preferable to vertical centering. – Mico May 1 '17 at 7:12

Personally I would use ltablex (makes tabularx a "longtable") and then the tabularx colummns (as you want to use tabularx eitherway). Here's a picture of the output (with showframe, so you can see that it fits the margin):

  • Thanks for your help! How would I go about vertically centering the text in the table? – kayco May 1 '17 at 7:05
