Wrong column spacing due to multicolumn in latex

问题

in the LaTeX table below, the third column gets too way much spacing due to the long \multicolumn cell in the last line. Can anyone think of a way of getting LaTeX to distribute the additional spacing needed evenly across columns?

\documentclass[11pt]{article}
\usepackage{booktabs}

\begin{document}
\begin{table}[htbp]
\centering
\begin{tabular}{lrrr}
\toprule
 & ICE-GB & ICE-SING & ICE-EA \\ 
 \midrule
NP & 619 & 595 & 496 \\ 
\textbf{Arithmetic mean}& \textbf{1.36} & \textbf{1.33} & \textbf{1.22} \\ 
SD&0.73 & 0.71 & 0.53 \\ 
Variation coefficient& 0.54 & 0.52 & 0.44 \\ 
\midrule
Kruskal Wallis rank sum test&\multicolumn{3}{l}{$H = 16.3941, df = 2, p= 0.0002755123$} \\ 
\bottomrule
\end{tabular}
\end{table}
\end{document}

Thanks!

Excess width \multicolumns end up assigning the excess to the last column. You can avoid this by either using a fixed-width \multicolumn - that is, use a p{<len>} column, or for even spreading of columns use a fixed-width column for the non-\multicolumn columns:

\documentclass[11pt]{article}
\usepackage{booktabs,array}

\begin{document}
\noindent
\begin{tabular}{l*{3}{>{\raggedleft\arraybackslash}p{5em}}}
  \toprule
  & ICE-GB & ICE-SING & ICE-EA \\ 
  \midrule
  NP & 619 & 595 & 496 \\
  \textbf{Arithmetic mean}     & \textbf{1.36} & \textbf{1.33} & \textbf{1.22} \\ 
  SD                           & 0.73          & 0.71          & 0.53 \\ 
  Variation coefficient        & 0.54          & 0.52          & 0.44 \\ 
  \midrule
  Kruskal Wallis rank sum test & \multicolumn{3}{r}{$H = 16.3941, df = 2, p= 0.0002755123$} \\ 
  \bottomrule
\end{tabular}
\end{document}

In the above example, the last three columns each have width 5em, and are \raggedleft (similar to an r-column specification).
