Longtable indentation in first column

I'm having trouble getting the text alignment in the first column of my longtable right.

The problem is, that after a linebreak (automatic) the text is indented. More like reverse indented, since it is aligned more to the left than the first line. I want to avoid that, but can't find a solution that works. I have tried redefining via \newcolumntype and some other stuff for the last three hours and am now officially giving up :D I hope somebody can help.

This is my MWE, where the odd alignment occurs right in the first row:

Thanks so much!

• Welcome to TeX.SE! I believe the problem comes from your \rule[-1ex]{0pt}{2.5ex} commands, what are they good for? – user121799 Jun 19 '18 at 21:36
• I have to admit that I don't know. I used the table assistant in Texmaker to get the rough structure of the table. I just tried and deleted the \rule... stuff. Works fine now. That was easy :D Thank you so much! – Mina Meer Jun 19 '18 at 21:40
• iot seems that \rule[-1ex]{0pt}{2.5ex} serve as strut by which is added some vertical space. if you remove space between them and following text, the indentation for one space will disappear. however, instead this rules you can use more elegant solutions, for example gaped cells from the package makecell. – Zarko Jun 19 '18 at 21:52

which gives

about rules used in your table, read my comment below your question.

edit: added are code for table head, last head, foot and last foot. slightly decreased is \arraystreatch (that rows become more compact) and increased vertical spaces in cells. now the rows are better visible and use lines between rows is superfluous.

• Although this solution looks really nice, I think I will use a version with hlines. I have some tables with seven columns (using landscape to make it fit) and find it easier to read with hlines in between rows. I was wondering if it is possible in your example to add the headings on each page. That's what \endhead does in the other example, right? When I add it after \toprule I don't get an error or something, but also no headings on the following page. – Mina Meer Jun 20 '18 at 9:03
• @MinaMeer, yes it is possible. i will add this to my answer asap. – Zarko Jun 20 '18 at 10:09
• @MinaMeer, see edited answer. – Zarko Jun 20 '18 at 10:43
• I used this template for all my tables and I like it a lot. I have a problem with a very broad table, though, that I put into a landscape environment. I adjusted my captions like this: \usepackage[labelfont=bf,singlelinecheck=false,format=plain,,justification=raggedright,indention=0cm]{caption} It worked fine so far, but not in the landscape environment. The caption is shifted to the left and it looks like the table does not use all the space on the page, but less than textwidth or textheight (?) in that case. If it helps, I could post an example below. Thank you! – Mina Meer Jul 4 '18 at 8:40
• (i) try replace all \textwidth with \linewidth (as i did in edited answer). (ii) caption with your settings had to be aligned at left text border. – Zarko Jul 4 '18 at 8:46

Getting rid of the mysterious \rule[-1ex]{0pt}{2.5ex} directives is a good first step. If you look closely, you'll notice that the longtable is wider than the textblock; it's necessary to reduce some of the column widths. Also, do change from full justification to raggedright layout in all three columns.

• Thanks, this is even better. I really appreciate the effort =) – Mina Meer Jun 20 '18 at 8:55
