如何使用 longtable 删除 pgfplotstable 中的多重定义标签

tag-icon • tag-icon cross-referencing longtable pgfplotstable labels
如何使用 longtable 删除 pgfplotstable 中的多重定义标签

我需要为longtable可能带有标签的文本添加标题以供引用，但是 SIAM 格式在遇到重复定义的标签时会失败，因为标题重复。有没有简单的方法可以为第一个标题添加标签？

这是 MWE。第一次编译没有问题，但第二次编译出现此错误：

! SIAM Label Error: There were multiply-defined labels. Correct multiply-defined labels.

答案1

longtable允许指定\endfirsthead和\endhead。这些命令的用法在文档中显示pgfplotstable第 21 页也一样。

修改如下：

\makeatletter
\pgfplotstabletypeset[col sep=space,header=true,    
columns={Idx,Nam,Dim,Grd},      % display specified columns
columns/Idx/.style={fixed,fixed zerofill,precision=0,column type=r},
columns/Nam/.style={column type=l,string type},
columns/Dim/.style={fixed,fixed zerofill,precision=1,column type=r},
columns/Grd/.style={column type=l,string type},%
every head row/.append style={%
    typeset cell/.code={%
       \ifnum\c@pgfplotstable@colindex=1\relax
            \pgfkeyssetvalue{/pgfplots/table/@cell content}{
                             \caption{A caption}\label{aLabel}\\\toprule ##1 \gdef\@tempa{\caption*{A caption}\\\toprule ##1&} &}%
       \else
        \ifnum\c@pgfplotstable@colindex=\c@pgfplotstable@numcols\relax
            \pgfkeyssetvalue{/pgfplots/table/@cell content}{##1\g@addto@macro\@tempa{ ##1\\\midrule\endhead}\\\midrule\endfirsthead\@tempa}%
                        \@tempa
        \else
            \pgfkeyssetvalue{/pgfplots/table/@cell content}{##1\g@addto@macro\@tempa{ ##1&} & }%
        \fi
           \fi
    },
},
 every last row/.style={after row=\bottomrule}
]{testdata.dat}
\makeatother
