# What is wrong with this code?

\hline \hline
\cline{1-2}
Område & Area & x & y & $Ax$ & $Ay$ \\
\hline \hline
Triangeln & 157,5 & 14,83 & 6 & 2335,25 & 945 \\

How do I fix this? All my variables doesn't fit in the table.

• 1) {llr} means three columns ... left,left and right aligned .... You need six columns and not 3. 2) Use \centering (no argument for \centering) instead of \centerline{...} – koleygr Oct 5 '20 at 15:21
• Ahaa, what's the code for 6 columns? – Muhashka Oct 5 '20 at 15:24
• @oni thank you! – Muhashka Oct 5 '20 at 15:27
• could be {llllll} or {lrrrrr} etc .... Also there are columns like p{2cm} or m{2cm} ... l means left ... r means right ... c means centered in the cells.... p{2cm} is a column with automatic breaks and width of 2 cm m{2cm} is like p but verticlay centered – koleygr Oct 5 '20 at 15:27
• Yeah got it, btw how can I make my variables be at center in the table, I mean "Område & Area & x & y & $Ax$ & $Ay$ \\" these, they are not in center if you understand what I mean. Well "Område & Area" these are but the rest are not. – Muhashka Oct 5 '20 at 15:45

You need to specify as many columns as you use in the table.

Do yourself a favor and learn a bit of siunitx for this kind of tables, so the numbers will line up perfectly. I also recommend booktabs for the better rules.

I lined up also the input, but it's not required: it's just easier to read the code and maybe fix faulty entries.

Note that \centerline is the wrong tool and a simple \centering declaration is better.

\documentclass{article}
\usepackage[T1]{fontenc}
\usepackage[swedish]{babel}

\usepackage{booktabs} % better tables
\usepackage{siunitx}  % numeric tables and more

\sisetup{output-decimal-marker={,}}

You need to add more columns to your table. \begin{tabular}{llrlll} … \end{tabular}

\begin{table}[!ht]
\centering{\begin{tabular}{llrlll}
\hline \hline
\cline{1-2}
Område & Area & x & y & $Ax$ & $Ay$ \\
\hline \hline
Triangeln & 157,5 & 14,83 & 6 & 2335,25 & 945 \\
Halvcirkeln & 127,17 & 5,18 & 9 & 658,78 & 1144,53 \\
\hline
\end{tabular}}
