Question

我有一个很大的数据集（不是很大）。我正在使用“选择打印”选项。

输出格式非常糟糕。我该如何解决？

一些dataTable.js信息 我的表还具有一个下拉过滤器默认情况下，导出按钮（包括“打印”）将自动检测是否选择了任何行（通过DataTables的Select扩展名），并且仅从这些选定的行中导出数据。如果未选择任何行，则将导出所有行。

如果您希望自定义此行为，则可以使用exportOptions对象来确定打印数据中包含哪些列和行。可以使用exportOptions.modifier选项指定一个DataTables选择器-修改器对象，该对象可以确定打印表的顺序以及是否包括过滤行，以及其他操作。
