The first row in my longtable-environment should be left-aligned and only have a specific width. The other rows should be right-aligned. I get the error Extra alignment tab has been changed to \cr 1 & if I use >{\raggedleft}p{1cm} instead of only p{1cm}. What is wrong with my environment?

Is there also a way to align the \cmidrule centered in the middle of the whole table? An extra table in a minipage-environment does not really work (the minipage is then right-aligned).

  • Welcome to TeX.SE! Your write-up, I'm afraid, is a bit confusing. Are you trying the left- or right-align the contents of entire rows (which is what you write) or columns? Please clarify.

  • Sorry for the inconvenience. It is a bit difficult for me to explain the problem. The first row (with the words) should be left-aligned. The other rows (with the numbers) should be right-aligned (but the first column should be left-aligned in each case). But additionally, the gap between the numbers should not be so big -- especially for the last column. Due to the width of the last column in the first row (the words...) I get a large gap between e.g. "3684 &79".

The problem is well known and documented in the package array: if you have >{\raggedleft} in the last column either you use \tabularnewline for ending the row or say


It's also wrong to specify p{1cm} in the table preamble, while using p{3cm} in the \multicolumn: use the same dimension in both places.
