在处理跨多个 PDF 页面扩展的 HTML 表格时，确保表头在每个新页面的顶部重复是很重要的。 IronPDF 的 CssMediaType.Print 选项帮助实现此行为。

// Set the CSS media type to 'Print' to ensure table headers repeat on every new page
Renderer.RenderingOptions.CssMediaType = IronPdf.Rendering.PdfCssMediaType.Print;

// Set the CSS media type to 'Print' to ensure table headers repeat on every new page
Renderer.RenderingOptions.CssMediaType = IronPdf.Rendering.PdfCssMediaType.Print;

' Set the CSS media type to 'Print' to ensure table headers repeat on every new page
Renderer.RenderingOptions.CssMediaType = IronPdf.Rendering.PdfCssMediaType.Print

相反，使用 CssMediaType.Screen 将导致 Chrome 仅在表格的最开始打印一次表头。

// Set the CSS media type to 'Screen' if you want the headers printed only once at the start of the table
Renderer.RenderingOptions.CssMediaType = IronPdf.Rendering.PdfCssMediaType.Screen;

// Set the CSS media type to 'Screen' if you want the headers printed only once at the start of the table
Renderer.RenderingOptions.CssMediaType = IronPdf.Rendering.PdfCssMediaType.Screen;

' Set the CSS media type to 'Screen' if you want the headers printed only once at the start of the table
Renderer.RenderingOptions.CssMediaType = IronPdf.Rendering.PdfCssMediaType.Screen
