如何修改OpenXML TableCell的前景色和背景色？

Question

我正在创建表格单元格如下：

private static TableCell GetHeaderCell(string cellText)
{
    var tc = new TableCell(new Paragraph(new Run(new Text(cellText))));
    return tc;
}

我希望它是白色文字的蓝色。

我尝试了以下内容，但它不起作用;当我尝试打开文档时，我收到错误，内容有问题：

private static TableCell GetHeaderCell(string cellText)
{
    var props = new TableCellProperties();
    var solidFill = new SolidFill();
    var rgbColorHex = new RgbColorModelHex() { Val = "FF0000" };//Red Background for Single TableCell.

    solidFill.Append(rgbColorHex);        
    props.Append(solidFill);

    var paragraph = new Paragraph(new Run(new Text(cellText)));

    var tc = new TableCell(paragraph, props);

    return tc;
}

完整错误如下：

这是一个两部分问题：

1）如何修改OpenXML TableCell的前景

OpenXML TableCell的前景由Run的属性定义，称为RunProperties。要为运行添加颜色，您必须使用Color属性添加Val对象。

// Create the RunProperties object for your run
DocumentFormat.OpenXml.Wordprocessing.RunProperties rp = 
    new DocumentFormat.OpenXml.Wordprocessing.RunProperties();
// Add the Color object for your run into the RunProperties
rp.Append(DocumentFormat.OpenXml.Wordprocessing.Color() { Val = "ABCDEF" }); 
// Create the Run object
DocumentFormat.OpenXml.WordProcessing.Run run = 
    new DocumentFormat.OpenXml.WordProcessing.Run();
// Assign your RunProperties to your Run
run.RunProperties = rp;
// Add your text to your Run
run.Append(new Text("My Text"));

请参阅reference question。

2）如何修改OpenXML TableCell的背景

可以使用TableCell修改TableCellProperties背景，类似于使用Run的上述RunProperties。但是，您将Shading对象应用于TableCellProperties。

// Create the TableCell object
DocumentFormat.OpenXml.Wordprocessing.TableCell tc = 
    new DocumentFormat.OpenXml.Wordprocessing.TableCell();
// Create the TableCellProperties object
TableCellProperties tcp = new TableCellProperties(
    new TableCellWidth { Type = TableWidthUnitValues.Auto, }
);
// Create the Shading object
DocumentFormat.OpenXml.Wordprocessing.Shading shading = 
    new DocumentFormat.OpenXml.Wordprocessing.Shading() {
    Color = "auto",
    Fill = "ABCDEF",
    Val = ShadingPatternValues.Clear
};
// Add the Shading object to the TableCellProperties object
tcp.Append(shading);
// Add the TableCellProperties object to the TableCell object
tc.Append(tcp);

// also need to ensure you include the text, otherwise it causes an error (it did for me!)
tc.Append(new Paragraph(new Run(new Text(cellText))));

Answer 2

DocumentFormat.OpenXml.WordProcessingRunProperties rp = 
    new DocumentFormat.OpenXml.WordProcessingRunProperties();

=

DocumentFormat.OpenXml.WordProcessing.RunProperties rp = 
    new DocumentFormat.OpenXml.WordProcessing.RunProperties();
