Tables in landscape mode

Question

I need to show Excell table below in landscpe mode including the colours of each cell.

I have used \begin{landscape} and \end{landscape} but I couldn't fix all the data in the same page.

Also I used the software excel2latex (http://www.ctan.org/pkg/excel2latex) still I didn't get the colours in the cell. So any suggestions to do this?

Code using excel2latex

Answer 1

The table you want will be nearly illegible given default page margins. Related post: What is the recommended font to use for a statistical table in an academic journal?. I'd strongly recommend coming up with a different table design, or compromising elsewhere (for example, do you need 7-8 significant digits on your values?).

MWE with widest numbers from each column placed side by side to show worst-case spacing, and using booktabs and siunitx:
