LaTeX - left align a table (ie not centred) from the preamble?

Question

I'm making a document in LaTeX, but I can only change the preamble of the document. Inside this document I have tables, made with the longtable environment. By default LaTeX centres each table in the middle of the page. Is there anyway to make the tables be left aligned, given that I can only change the preamble?

Solution

From the documentation

The optional argument of longtable controls the horizontal alignment of the table. The possible options are [c], [r] and [l], for centring, right and left adjustment, respectively. Normally centring is the default, but this document specifies

  \setlength\LTleft\parindent
  \setlength\LTright\fill

in the preamble, which means that the tables are set flush left, but indented by the usual paragraph indentation.

The link to the documentation point to a version of 1996/11/12. On CTAN you will find one of 2004/02/01: tug.ctan.org/tex-archive/macros/latex/required/tools/…
