VerticalMerge

CellFormat.VerticalMerge property

Specifies how the cell is merged with other cells vertically.

public CellMerge VerticalMerge { get; set; }

Remarks

Cells can only be merged vertically if their left and right boundaries are identical.

When cells are vertically merged, the display areas of the merged cells are consolidated. The consolidated area is used to display the contents of the first vertically merged cell and all other vertically merged cells must be empty.

Examples

Prints the horizontal and vertical merge type of a cell.

public void CheckCellsMerged()
{
    Document doc = new Document(MyDir + "Table with merged cells.docx");
    Table table = doc.FirstSection.Body.Tables[0];

    foreach (Row row in table.Rows)
        foreach (Cell cell in row.Cells)
            Console.WriteLine(PrintCellMergeType(cell));
}

public string PrintCellMergeType(Cell cell)
{
    bool isHorizontallyMerged = cell.CellFormat.HorizontalMerge != CellMerge.None;
    bool isVerticallyMerged = cell.CellFormat.VerticalMerge != CellMerge.None;
    string cellLocation =
        $"R{cell.ParentRow.ParentTable.IndexOf(cell.ParentRow) + 1}, C{cell.ParentRow.IndexOf(cell) + 1}";

    if (isHorizontallyMerged && isVerticallyMerged)
        return $"The cell at {cellLocation} is both horizontally and vertically merged";
    if (isHorizontallyMerged)
        return $"The cell at {cellLocation} is horizontally merged.";

    return isVerticallyMerged ? $"The cell at {cellLocation} is vertically merged" : $"The cell at {cellLocation} is not merged";
}

Shows how to merge table cells vertically.

Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);

// Insert a cell into the first column of the first row.
// This cell will be the first in a range of vertically merged cells.
builder.InsertCell();
builder.CellFormat.VerticalMerge = CellMerge.First;
builder.Write("Text in merged cells.");

// Insert a cell into the second column of the first row, then end the row.
// Also, configure the builder to disable vertical merging in created cells.
builder.InsertCell();
builder.CellFormat.VerticalMerge = CellMerge.None;
builder.Write("Text in unmerged cell.");
builder.EndRow();

// Insert a cell into the first column of the second row. 
// Instead of adding text contents, we will merge this cell with the first cell that we added directly above.
builder.InsertCell();
builder.CellFormat.VerticalMerge = CellMerge.Previous;

// Insert another independent cell in the second column of the second row.
builder.InsertCell();
builder.CellFormat.VerticalMerge = CellMerge.None;
builder.Write("Text in unmerged cell.");
builder.EndRow();
