Lyx wiki 建议，如果我想tabularx在使用 GUI 构建的表时使用，我可以使用以下序言：
%% Hack by Heiko Oberdiek (on de.comp.text.tex)
\usepackage{tabularx}
%% Redefine the standard table
\let\ORIGtabular\tabular
\let\ORIGendtabular\endtabular
\let\ORIGtabularx\tabularx
\renewcommand*{\tabularx}{%
\def\tabular{%
\let\endtabular\ORIGendtabular
\ORIGtabular
}%
\ORIGtabularx
}
\renewcommand{\tabular}{%
%% The width of the table. Adjust if needed
\tabularx{\linewidth}%
}
\renewcommand{\endtabular}{\endtabularx}
我很喜欢这个tabulary包，想重现上面的替换，但要用tabulary代替。但是，简单地用 代替tabularx上面tabulary的 不起作用。有没有办法让它起作用，或者 的设计tabulary与这种替换不兼容？
