是否可以在两行之间拆分条目(一行中是参考资料,另一行中是页码)?我有一个包含长条目的索引,我发现这种情况从未发生过,这会导致出现大片空白。
以下是 MWE:
\begin{filecontents*}{\jobname.mst}
item_0 "\n\n \\item "
item_1 " \\firstlevel "
item_2 " \\secondlevel "
item_01 " \\firstlevel "
item_x1 " \\firstlevel "
item_12 " \\secondlevel "
item_x2 " \\secondlevel "
delim_0 ":~"
delim_1 ":~"
delim_2 ":~"
\end{filecontents*}
