减少 ThreePartTable 和 Caption 之间的空间

Question

我在需要处理长表格的环境xltabular中有一个。但与我之前的设计相比，表格和下面的标题之间的空间变得太大了。有人知道我该如何减少这个空间吗？ThreePartTabletabularxthreeparttable

\documentclass[a4paper,10pt,notitlepage]{article}   % papersize, fontsize, documentclass; 
\usepackage{xltabular}
\usepackage[flushleft]{threeparttablex}     % to have a dedicated notes section after tables
\usepackage[font=small, margin=0pt]{caption}            % table and figure captions
\usepackage[table]{xcolor}                  % used for table alternatively colors
\usepackage{booktabs}                       % use package booktabs for easy creating tables

% Spacing and margin rules

\setlength{\fboxrule}{1pt}%
\setlength{\abovecaptionskip}{7pt}

    }

更新：
我发现的一个解决方案是\setlength{\abovecaptionskip}{0pt}直接将另一个添加到 中tableenv。如果有人有更好的解决方案，我会很感兴趣！
