如何在该表中创建相等的列宽？

如何在该表中创建相等的列宽？

我正在用 latex 制作回归输出表。但是，由于重要性，使用\multicolumnlatex 的下标将所有额外的宽度放在最后一列。我希望列宽相同，我该怎么做？

这是我的代码：

答案2

除了将表格脚注材料的宽度固定为环境宽度tabular（这一目标可以通过使用包的机制轻松实现）之外threeparttable，您还应该将三个数据列中的数字与各自的小数点对齐。我建议您使用包dcolumn的机制来实现您的第二个目标。

\documentclass{article}
\usepackage{array,booktabs,dcolumn}
\newcolumntype{d}[1]{D..{#1}}
\newcommand\mc[1]{\multicolumn{1}{c}{#1}}

\usepackage[flushleft]{threeparttable}
