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?
\documentclass[12pt,a4paper,oneside,openright]{book}
\usepackage[hmargin=3cm,vmargin=3cm,bindingoffset=0.5cm]{geometry}
\usepackage{siunitx}
\begin{document}
\begin{table}[htp]

Best Answer
The table fits in the margins, without need of setting
\small
and of reducing too much\tabcolsep
with the following code. Note thekey, which states precisely the space you need. This means:
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).
