在将电子表格渲染为HTML时设置默认字体

Aspose.Cells允许在将电子表格渲染为HTML时设置默认字体. 请使用HtmlSaveOptions.DefaultFontName来实现此目的. 当电子表格中有一些单元格具有无效或不存在的字体时, 特定于HtmlSaveOptions.DefaultFontName属性指定的字体将进行渲染.

在将电子表格渲染为HTML时设置默认字体

以下示例代码创建一个工作簿，并在第一个工作表的B4单元格中添加了一些文本，并将其字体设置为某个未知/不存在的字体。然后，它通过设置不同的默认字体名称，如Courier New、Arial、Times New Roman等，将工作簿保存为HTML。

截图显示了通过HtmlSaveOptions.DefaultFontName属性设置不同默认字体名称的效果.

该代码生成了使用Courier New的output HTML文件, 使用Arial的output HTML文件, 以及使用Times New Roman的output HTML文件.

示例代码

// For complete examples and data files, please go to https://github.com/aspose-cells/Aspose.Cells-for-.NET
// The path to the documents directory.
string dataDir = RunExamples.GetDataDir(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);
            
// Create workbook object and access first worksheet.
Workbook wb = new Workbook();
Worksheet ws = wb.Worksheets[0];

// Access cell B4 and add some text inside it.
Cell cell = ws.Cells["B4"];
cell.PutValue("This text has some unknown or invalid font which does not exist.");

// Set the font of cell B4 which is unknown.
Style st = cell.GetStyle();
st.Font.Name = "UnknownNotExist";
st.Font.Size = 20;
cell.SetStyle(st);

// Now save the workbook in html format and set the default font to Courier New.
HtmlSaveOptions opts = new HtmlSaveOptions();
opts.DefaultFontName = "Courier New";
wb.Save(dataDir + "out_courier_new_out.htm", opts);

// Now save the workbook in html format once again but set the default font to Arial.
opts.DefaultFontName = "Arial";
wb.Save(dataDir + "out_arial_out.htm", opts);

// Now save the workbook in html format once again but set the default font to Times New Roman.
opts.DefaultFontName = "Times New Roman";
wb.Save(dataDir + "times_new_roman_out.htm", opts);
