# tabular, small detail

Could you please kindly help me to break the blue boxes (see picture) to the next line so that the Table is narrower? Than you very much for your help!

• use @{}lp{20mm}l@{} as column declaration (play with the 20mm). Maybe you'll need to add \raggedright at the beginning of the breaking cells afterwards. – Lupino Feb 8 at 11:55
• please extend your code snipet to complete small document which produce your table (where is define \degree?). one solution is use tabularx environment: \begin{tabularx}{\linewidth}{@{} l X X @{}} – Zarko Feb 8 at 12:00

• please always provide mwe (minimimal working example), a small complete document beginning with \documentclass{...}, with necessary preamble with loaded packages and defined new commands for your problem, body of document and ending with \end{document}. with this you will help us to help you (preparing a mwe can serve you at finding solution yourself)
• your problem can be solved with using for the second column the column type which enable to break cells' contents into more line as is p{<widt>} or X from tabularx package
• i try to reconstruct from your code snippet an mwe in which i employ tabularx and siunitx package. in this i try to remedy your code from errors ( also it is easy to lost in it):
