将 Excel 转为 PDF 时渲染实线格线

为了兼容旧版本，Aspose.Cells在将Excel转换为PDF时默认将网格线渲染为点线。然而，现代Excel中网格线已渲染为实线。

通过选项 PdfSaveOptions.GridlineTypes，Aspose.Cells也可以将网格线渲染为实线。

// Create an empty Workbook
Workbook wb = new Workbook();

//Prepare data
wb.getWorksheets().get(0).getCells().get("D9").putValue("gridline");

//Enable to print gridline
wb.getWorksheets().get(0).getPageSetup().setPrintGridlines(true);

//Set to render gridline as solid line
PdfSaveOptions pdfSaveOptions = new PdfSaveOptions();
pdfSaveOptions.setGridlineType(GridlineType.HAIR);

// Save the pdf file with PdfSaveOptions
wb.save("output.pdf", pdfSaveOptions);
