向Word文档中的现有表添加一行(打开XML)

Question

我需要使用现有表(例如,3列)打开现有Word文档(.docx)并向该表添加新行.有没有办法做到这一点？我正在使用Open XML

我正在创建这样的表(第一次):

Table tbl = new Table();

// Set the style and width for the table.
TableProperties tableProp = new TableProperties();
TableStyle tableStyle = new TableStyle() { Val = "TableGrid" };

// Make the table width 100% of the page width.
TableWidth tableWidth = new TableWidth() { Width = "5000", Type = TableWidthUnitValues.Pct };

// Apply
tableProp.Append(tableStyle, tableWidth);
tbl.AppendChild(tableProp);

// Add 3 columns to the table.
TableGrid tg = new TableGrid(new GridColumn(), new GridColumn(), new GridColumn());
tbl.AppendChild(tg);

// Create 1 row to the table.
TableRow tr1 = new TableRow();

// Add a cell to each column in the row.
TableCell tc1 = new TableCell(new Paragraph(new Run(new Text("1"))));
TableCell tc2 = new TableCell(new Paragraph(new Run(new Text("2"))));
TableCell tc3 = new TableCell(new Paragraph(new Run(new Text("3"))));
tr1.Append(tc1, tc2, tc3);

// Add row to the table.
tbl.AppendChild(tr1);
return tbl;

Answer 1

干得好,

Body bod = doc.MainDocumentPart.Document.Body;
foreach (Table t in bod.Descendants<Table>())
{
    t.Append(new TableRow(new TableCell(new Paragraph(new Run(new Text("test"))))));
}

使用LINQ获取正确的表.

编辑:

假设您想要获得包含4列的表.

Body bod = doc.MainDocumentPart.Document.Body;
foreach (Table t in bod.Descendants<Table>().Where(tbl => tbl.GetFirstChild<TableRow>().Descendants<TableCell>().Count() == 4))
{
    t.Append(new TableRow(new TableCell(new Paragraph(new Run(new Text("test"))))));
}

假设您要获取包含单词"mytable"的表格.

Body bod = doc.MainDocumentPart.Document.Body;
foreach (Table t in bod.Descendants<Table>().Where(tbl => tbl.InnerText.Contains("myTable")))
{
    t.Append(new TableRow(new TableCell(new Paragraph(new Run(new Text("test"))))));
}

下面是一个更详细的示例,您可以在现有表中添加5行.

这假设该表是文档中的第一个表.如果没有,你必须找到你的桌子.

代码获取表的最后一行并复制它.之后,您只需要在单元格中填写数据.

Table myTable = doc.Body.Descendants<Table>().First();
TableRow theRow = myTable.Elements<TableRow>().Last();
for (int i = 0; i < 5; i++)
{
    TableRow rowCopy = (TableRow)theRow.CloneNode(true);

    var runProperties = GetRunPropertyFromTableCell(rowCopy, 0);
    var run = new Run(new Text(i.ToString() + " 1"));
    run.PrependChild<RunProperties>(runProperties);

    rowCopy.Descendants<TableCell>().ElementAt(0).RemoveAllChildren<Paragraph>();//removes that text of the copied cell
    rowCopy.Descendants<TableCell>().ElementAt(0).Append(new Paragraph(run));
    //I only get the the run properties from the first cell in this example, the rest of the cells get the document default style. 
    rowCopy.Descendants<TableCell>().ElementAt(1).RemoveAllChildren<Paragraph>();
    rowCopy.Descendants<TableCell>().ElementAt(1).Append(new Paragraph(new Run(new Text(i.ToString() + " 2"))));
    rowCopy.Descendants<TableCell>().ElementAt(2).RemoveAllChildren<Paragraph>();
    rowCopy.Descendants<TableCell>().ElementAt(2).Append(new Paragraph(new Run(new Text(i.ToString() + " 3"))));

    myTable.AppendChild(rowCopy);
}
myTable.RemoveChild(theRow); //you may want to remove this line. I have it because in my code i always have a empty row last in the table that i copy.

GetRunPropertiesFromTableCell是我尝试使用与现有行相同的文本格式的快速黑客尝试.

private static RunProperties GetRunPropertyFromTableCell(TableRow rowCopy, int cellIndex)
{
    var runProperties = new RunProperties();
    var fontname = "Calibri";
    var fontSize = "18";
    try
    {
        fontname =
            rowCopy.Descendants<TableCell>()
               .ElementAt(cellIndex)
               .GetFirstChild<Paragraph>()
               .GetFirstChild<ParagraphProperties>()
               .GetFirstChild<ParagraphMarkRunProperties>()
               .GetFirstChild<RunFonts>()
               .Ascii;
    }
    catch
    {
    //swallow
    }
    try
    {
        fontSize =
               rowCopy.Descendants<TableCell>()
                  .ElementAt(cellIndex)
                  .GetFirstChild<Paragraph>()
                  .GetFirstChild<ParagraphProperties>()
                  .GetFirstChild<ParagraphMarkRunProperties>()
                  .GetFirstChild<FontSize>()
                  .Val;
    }
    catch 
    {
    //swallow
    }
    runProperties.AppendChild(new RunFonts() { Ascii = fontname });
    runProperties.AppendChild(new FontSize() { Val = fontSize });
    return runProperties;
}
