這是來自一個較舊的問題，但我想知道如何更改下面的程式碼以使數量選項卡顯示“項目”而不是“小時”？
\documentclass{invoice}
\def \tab {\hspace*{3ex}}
\begin{document}
\hfil{\Huge\bf Initech Inc.}\hfil
\bigskip\break % Whitespace
\hrule % Horizontal line
123 Broadway \hfill (000) 111-1111 \\
City, State 12345 \hfill [email protected]
\\ \\
{\bf Invoice To:} \\
\tab James Smith \\ % Invoice recipient
\tab Generic Corporation \\ % Recipient's company
{\bf Date:} \\
\tab \today \\
\begin{invoiceTable}
\feetype{Consulting Services}
\hourrow{October 3, 2012}{8}{12}
\hourrow{October 4, 2012}{6.5}{12}
\hourrow{October 5, 2012}{5.25}{12}
\hourrow{October 10, 2012}{9.75}{20}
\hourrow{October 11, 2012}{5}{12.51}
\feetype{Accounting Services} % Fee category description

您可以使用\unitrow如下 MWE 所示的命令：
\documentclass{發票}
\def \tab {\hspace*{3ex}}
\begin{document}
\begin{invoiceTable}
\feetype{Consulting Services}
\unitrow{October 3, 2012}{8}{12}{items}
\hourrow{October 4, 2012}{6.5}
\end{invoiceTable}
\end{document}
