删除单元格边框后无法读取的Word文档（OpenXml.Wordprocessing）

Question

After creating a TableCellProperties and removing the TableCellBorders , the word document becomes unreadable and I get:

Word found unreadable content in test.docx. Do you want to recover the contents of this document? If you trust the source of this document, click Yes.

The code that I use:

TableCellProperties cellProp = new TableCellProperties(
    new TableCellBorders(
        new TopBorder()
        {
            Val =
                new EnumValue<BorderValues>(BorderValues.Nil),
        },
        new BottomBorder()
        {
            Val =
                new EnumValue<BorderValues>(BorderValues.Nil),
        },
        new LeftBorder()
        {
            Val =
                new EnumValue<BorderValues>(BorderValues.Nil),

        },
        new RightBorder()
        {
            Val = new EnumValue<BorderValues>(BorderValues.Nil),
        }
    )
);
TableCell tc = new TableCell();


tc.Append(cellProp);

TableRow trTest = new TableRow();
trTest.Append(new TableCell(tc.OuterXml));
trTest.Append(new TableCell(new Paragraph(new Run(new Text("B")))));
trTest.Append(new TableCell(new Paragraph(new Run(new Text("C")))));
trTest.Append(new TableCell(new Paragraph(new Run(new Text("D")))));
trTest.Append(new TableCell(new Paragraph(new Run(new Text("E")))));
trTest.Append(new TableCell(new Paragraph(new Run(new Text("F")))));
t.Append(trTest);

The BorderValue is set to Nil , since None does not seem to remove the borders. After the MS Word auto recover procedure, the file is fine. Whan can cause such an issue?

Answer 1

Problem solved!

Each table cell should contain/end with Paragraph object, so the solution is:

tc.Append(cellProp);
tc.Append(new Paragraph());

Looks like I have the same problem like in this question , but without the error.
