# Longtable margin

I use the package longtable for build tables. But the table has many columns, then it to fall outside the limits page. How do I fix this? And how to change the margin for tables?

Look at the example:

Thanks.

use package `ltablex` or `ltxtable`. Documentations are available by running `texdoc <package name>` –  Herbert Jun 3 '12 at 8:20

``````\setlength\LTleft{-1cm}
alternatives are to use a smaller font, for example putting `\small` before the `longtable`. Also you have not shown your TeX code but it looks like you have used `c` columns. As in a standard `tabular` `c` columns never wrap over a line automatically, so you may want to make some of your columns fixed width with `p{3cm}` or whatever width is suitable, then TeX will linebreak and justify the entries to that width.
