调整列宽 tabularx + 表格边距

从以下 MWE 中可以看出，单独调整几列的宽度确实很棒。此外，如果需要，我该如何减少表格的页边距？

这会使某些列比其他列更宽，使所有列左右不平整，并使表格比页面更宽。您可能需要摆弄数字以获得所需的外观： 在此处输入图片描述

}
    \addlinespace
    \toprule
    \multicolumn{1}{c}{Variable } & Source & Spatial coverage & Temporal coverage & Frequency \\
    \midrule
    Urban Social Disturbances & USDAA, PRIO, Oslo & 55 cities (49 countries) & 1960-2010 & Event-based \\
    Local food prices & FAO GIEWS database  & 43 markets (in common with USDAA) & 1990-Present (unbalanced) & Monthly \\
    Total population & WDI 2010, World Bank & 190 countries & 1960-2011 & Annual \\
    Urban population (as p.c. of total) & WDI 2010, World Bank & 190 countries & 1960-2011 & Annual \\

\end{table}%

对于更高级的列定义，您可以使用tabu。下面的代码使前两列的宽度是其他列的两倍。X[3,c]将为您提供一个居中的列，其宽度是 1 单位列的三倍，后者是根据表格宽度动态计算的（如您的示例中所示\textwidth）。

\usepackage{booktabs}
\usepackage{tabu}

\begin{table}[htbp]
  \centering
  \caption{Add caption}
    \begin{tabu} to \textwidth {X[2,l]
                                X[2,l]
                                X[1,l]
                                X[1,l]
                                X[1,l]}
    \addlinespace
    \toprule
    \multicolumn{1}{c}{Variable } & Source & Spatial coverage & Temporal coverage & Frequency \\
    \midrule
    Urban Social Disturbances & USDAA, PRIO, Oslo & 55 cities (49 countries) & 1960-2010 & Event-based \\
    \bottomrule
    \end{tabu}
    \label{tab:addlabel}%
\end{table}%
