I use tabulary package for automatic width adjustment, but I have a blank line in the first row.

enter image description here

\documentclass{article} \usepackage{tabulary} \begin{document} \begin{table}[htbp] \begin{tabulary}{1.0\textwidth}{L|L|L|L|L} \hline & \hbox{Name} & \hbox{Function} & \hbox{Properties} & \hbox{Relationships} \\\hline\hline 7 & \hbox{System Maintenance Database} & Stores all kinds of errors occurred during operation from all components in a specified way & Only error related information is stored & \\ 9 & Main Database & & \\ \hline \end{tabulary} \caption{Data elements} \label{data} \end{table} \end{document}

What's wrong? How do I remove it?

  • \hbox is not documented in the LaTeX manual and for a reason: its behavior can be surprising. But why do you think you need it? Commented Oct 26, 2013 at 19:39

You are trying to change the format of certain cells by using \hbox. The correct way to do this is to use \multicolumn:

I have unboxed your "System Maintenance Database" so the table fits on the page; if you want that unbroken, you should again use a \multicolumn

If you don't mind changing the style of your table a little bit, I'd advise using booktabs, it makes the table look much cleaner and nice. If you still want your own table fixed, let me know in a comment.

The command L{3cm}in the table header means that a certain column will have left-alignment and will have a width of 3cm. You're free to change that. Since the first column was a little number, I just wrote l which just gives the alignment, no width.

  • With booktabs look better, no doubt, but the real improvement in style was remove the vertical lines and double lines. :) Commented Oct 26, 2013 at 18:39
  • @Fran Indeed, but I think that in the documentation of the package itself it is advised to avoid vertical lines altogether. If I remember well. The advantage of booktabs is also that it provides some auto-spacing for the midrules. :D Commented Oct 26, 2013 at 19:12
  • Of course. It is a shame that does not work well with colored rows because this, but in other case tables are indeed more elegant with booktabs. Commented Oct 26, 2013 at 20:12
