# C#を使用してMS Wordドキュメントにテーブルに行を追加する方法

// Open MS Word Document
Document MSWordDocument = new Document(@"input.docx");

// Get the Table by index
Table tableToAddRowsTo = MSWordDocument.FirstSection.Body.Tables[0];

// Create a new Row class object
Row row = new Row(MSWordDocument);

// Add three Cells to Row's cells collection
for (int i = 0; i < 3; i++)
{
    Cell cell = new Cell(MSWordDocument);
    cell.AppendChild(new Paragraph(MSWordDocument));
    cell.FirstParagraph.Runs.Add(new Run(MSWordDocument, "Text in Cell " + i));
    row.Cells.Add(cell);
}

// Insert new Row after the first Row
tableToAddRowsTo.Rows.Insert(1, row);

// Clone an existing Row from Table
Row cloneOfRow = (Row)tableToAddRowsTo.FirstRow.Clone(true);

// Remove all content from all Cells
foreach (Cell cell in cloneOfRow)
{
    cell.RemoveAllChildren();
    cell.EnsureMinimum();
}

// Add multiple empty rows to the end of table
for (int i = 0; i < 10; i++)
{
    Row emptyRow = (Row)cloneOfRow.Clone(true);
    tableToAddRowsTo.Rows.Add(emptyRow);
}

// Save updated document
MSWordDocument.Save(@"output.docx");
