我是 LaTeX 的新手，在longtabu表格方面遇到了问题。我已将其设置为交替行颜色，效果很好。但是，这会使除第一页之外的所有页眉都变成交替颜色。为了解决这个问题，我尝试\multicolumn在页眉中添加一行，如下面的 MWE 所示。我还在\multicolumn页脚中添加了一行，结果相同。
\documentclass[12pt]{article}
\usepackage{geometry}
\usepackage{graphicx}
\usepackage{tabu,xcolor,colortbl}
\usepackage{caption}
\usepackage{array}
\usepackage[colorlinks = true,
linkcolor = blue,
urlcolor = blue,
citecolor = blue,
anchorcolor = blue]{hyperref}
\usepackage{longtable}
\begin{document}
\taburowcolors[2]{white .. blue!20}
\tabulinesep=6pt
\arrayrulewidth=1pt
\begin{longtabu}[h]{| m{1.75in} | m{1.5in} | m{2.75in} |}
\caption{This is the first page header} \label{Table:example}\\
\rowcolor{blue}\color{white}Column 1 & \color{white}Column 2 & \color{white}Column 3\\
\endfirsthead
\rowcolor{white}\multicolumn{3}{c}{Table~\ref{Table:example}: Continued from previous page}\\
%\caption{Continued from previous page}\\
\rowcolor{blue}\color{white}Column 1 & \color{white}Column 2 & \color{white}Column 3\\
\endhead
\hline
%\rowcolor{white} \multicolumn{3}{l}{Continued on next page}\\
\endfoot
\hline
\endlastfoot
This is Column 1 & This column describes Column 1 and is generally a little longer & This is a longer description that will take up a few lines of text in the table. It is really just a bunch of text. This really means nothing in this minimum working example other than to take up space in the table.\\

我能做些什么来消除这些错误？
谢谢

使用\cellcolor，而不是\rowcolor：
\begin{longtabu}{| >{\raggedright}m{1.75in} | >{\raggedright}m{1.5in} | >{\raggedright\arraybackslash}m{2.75i$
\caption{This is the first page header} \label{Table:example}\\
\rowcolor{blue}\color{white}Column 1 & \color{white}Column 2 & \color{white}Column 3\\
\endfirsthead
\multicolumn{3}{c}{\cellcolor{white}Table~\ref{Table:example}: Continued from previous page}\\[\bigskipamount]
\rowcolor{blue}\color{white}Column 1 & \color{white}Column 2 & \color{white}Column 3\\
\endhead
我设置了一个小边距只是为了避免表格超出宽度。\raggedright单元格不会抛出数十个Underfull \hbox警告。
