Table out of margin

Question

I created this table using siunitx package since values must to be represented in scientific notation. Unfortunately the table goes out of margin. How can I fix the issue?

Please always post complete documents showing all packages used, it makes it much easier to process locally and see (in this cas)e how far into the margin it is. — David Carlisle, Jan 10 '13 at 20:59
@DavidCarlisle I inserted \small. The table became smaller but is still out of margins — Mazzy, Jan 10 '13 at 21:02

The table fits in the margins, without need of setting \small and of reducing too much \tabcolsep with the following code. Note the

table-format=1.4e-1

key, which states precisely the space you need. This means:

one digit for the integer part
four decimal digits
the sign for the exponent part
one digit for the exponent

Your table-format=1.4e06 reserved six digits for the exponent.

To be honest, the table width is 413.00468pt, while the \textwidth is 412.56499pt, so the difference is .44pt, less than the \hfuzz value of 0.5pt (0.18mm).

After may years ... seems to be useful (my) answer on question how-to-make-a-column-specifier-which-combines-x-and-s, which was asked far later. Its adoption to this question is below.

Combination of tabularx table environment with combination of X (used for column headers in command \multicolumn{1}{... X}{...}) and S columns gives table width equal to text width and align of numbers as according to S column type:

(red lines show borders of page layout).
