我確認你報告的內容。一種解決方法是用空格" "代替“空”字符串，當然，在文本運行中添加“空格保留”。
另一種可能性是創建字符樣式并將其應用于表格單元格。事實證明，這比聽起來要棘手，因為樣式需要兩次應用于包含文本的單元格：一次應用于 ParagraphMarkRunProperties，一次應用于 RunProperties。對于空單元格，樣式只需要應用于 ParagraphMarkRunProperties。
實際上，經過反思，您可以對字體大小使用相同的方法......
我在下面的代碼中包含了這兩種方法。僅用于字體大小的注釋被注釋掉（四行）。
示例代碼假定單行四列表格的第三個單元格沒有內容。只有在有內容時才添加運行和文本信息。
private void btnCreateTable_Click(object sender, EventArgs e)
{
string filePath = @"C:\X\TestCreateTAble.docx";
using (WordprocessingDocument pkg = WordprocessingDocument.Open(filePath, true))
{
MainDocumentPart partDoc = pkg.MainDocumentPart;
Document doc = partDoc.Document;
StyleDefinitionsPart stylDefPart = partDoc.StyleDefinitionsPart;
Styles styls = stylDefPart.Styles;
Style styl = CreateTableCharacterStyle();
stylDefPart.Styles.AppendChild(styl);
Table t = new Table();
TableRow tr = new TableRow();
for (int i = 1; i <= 4; i++)
{
TableCell tc = new TableCell(new TableCellProperties(new TableCellWidth() { Type = TableWidthUnitValues.Dxa, Width = "500" }));
Paragraph para = new Paragraph();
ParagraphProperties paraProps = new ParagraphProperties();
ParagraphMarkRunProperties paraRunProps = new ParagraphMarkRunProperties();
RunStyle runStyl = new RunStyle() { Val = "Table9Point" };
paraRunProps.Append(runStyl);
// FontSize runFont = new FontSize() {Val = "18" };
// paraRunProps.Append(runFont);
paraProps.Append(paraRunProps);
para.Append(paraProps);

txt.Space = SpaceProcessingModeValues.Preserve;

RunStyle inRunStyl = (RunStyle) runStyl.Clone();
runProps.Append(inRunStyl);

run.Append(runProps);
run.Append(txt);
para.Append(run);
}
tc.Append(para);
tr.Append(tc);
}
t.Append(tr);
//Insert at end of document
SectionProperties sectProps = doc.Body.Elements<SectionProperties>().LastOrDefault();
doc.Body.InsertBefore(t, sectProps);
}
}
private Style CreateTableCharacterStyle()
{
Style styl = new Style()
{
CustomStyle = true,
StyleId = "Table9Point",
Type = StyleValues.Character,
