javascript - 如何复制数据表pdf文档所有页面中的消息

Question

我正在使用PDF和Excel等数据表导出功能。在 PDF 导出中，我有消息选项，它只显示在文档的一页中。但我希望在文档的每一页中都有它。

{
 extend: 'pdfHtml5',
 message:" Phase:  Phase1",
 filename: 'Tickets_List',
 footer: true,
 header:true,
}

请帮帮我。谢谢。

Answer 1

在检查了 DataTables 和 pdfMake 文档后，您不能更改每个页面上的标题，但可以删除它。

我建议您使用 header 属性，因为您可以更改大小和字体，并按页更改。

以下示例显示标题与标题相同的位置，具有自定义功能:
