我想在多个页面上显示它。我该怎么做？
答案1
你应该绝不使用eqnarray，参见eqnarray 与 align。但即使你喜欢它，在目前的情况下它也是无用的，因为它不能跨页面拆分。原因是eqnarray最终会创建以下结构（就原始命令而言）：
$$
\halign to \displaywidth{...}
$$
无论如何，这是牢不可破的。
对于您的应用程序，既然我们知道了eqnarray没什么用，您可以考虑tabular，但这也存在同样的问题。但是，有一个 ，longtable它允许跨页面拆分表格材料。
这里第一列是数学模式，右对齐
>{$}r<{$}<
前面是 ，@{}删除初始填充。后面是\quad--\quad（根据自己的喜好更改分隔符），然后是描述列，左对齐。@{}末尾也是一样，删除填充。
默认情况下，longtables 是水平居中的，但作用于\LTleft它并使其变为零将打印与左边距对齐的表格。
