在Windows 7上使用MiKTeX運行LyX。我試圖LyX的的 「Embedded Objects tutorial」 導出爲PDF格式,但得到這個錯誤:LyX:未定義的控制序列 hline
Undefined control sequence
\hline
The control sequence at the end of the top line
of your error message was never \def'ed. If you have
misspelled it (e.g., `\hobx'), type `I' and the correct
spelling (e.g., `I\hbox'). Otherwise just continue,
and I'll forget about whatever was undefined.
有問題的代碼似乎是
\let\myHlineC\hline
\renewcommand{\hline}
{\arrayrulecolor{red}\myHlineC\arrayrulecolor{black}}
(部分文件的2.11.2)。
可能或可能不相關:The document's preamble。
