Grid also offers more flexible resizing behavior than Table and lighter weight then a Table. It derives from the Panel element which is best used inside of forms. This article is mainly talk about how to merge cells in grid via Spire.PDF.
Prerequisite:
- Download Spire.PDF for .NET (or Spire.Office for .NET) and install it on your system.
- Add Spire.PDF.dll as reference in the downloaded Bin folder thought the below path: "..\Spire.PDF\Bin\NET4.0\ Spire.PDF.dll".
- Check the codes as below in C#:
Here are the detail steps:
Step 1: Create a new PDF document and add a new page.
PdfDocument doc = new PdfDocument(); PdfPageBase page = doc.Pages.Add();
Step 2: Add a new grid with 5 columns and 2 rows, and set height and width.
PdfGrid grid = new PdfGrid();
grid.Columns.Add(5);
float width = page.Canvas.ClientSize.Width - (grid.Columns.Count + 1);
for (int j = 0; j < grid.Columns.Count;j++)
{
grid.Columns[j].Width = width * 0.20f;
}
PdfGridRow row0 = grid.Rows.Add();
PdfGridRow row1 = grid.Rows.Add();
float height = 20.0f;
for (int i = 0; i < grid.Rows.Count; i++)
{
grid.Rows[i].Height = height;
}
Step 3: Draw the current grid.
grid.Draw(page, new PointF(0, 50));
Step 4: Set the font of the grid and fill some content in the cells. Use RowSpan and ColumnSpan to merge certain cells vertically and horizontally.
row0.Style.Font = new PdfTrueTypeFont(new Font("Arial", 16f, FontStyle.Bold), true);
row1.Style.Font = new PdfTrueTypeFont(new Font("Arial", 16f, FontStyle.Italic), true);
row0.Cells[0].Value = "Corporation";
row0.Cells[0].RowSpan = 2;
row0.Cells[1].Value = "B&K Undersea Photo";
row0.Cells[1].StringFormat = new PdfStringFormat(PdfTextAlignment.Center, PdfVerticalAlignment.Middle);
row0.Cells[1].ColumnSpan = 3;
row0.Cells[4].Value = "World";
row0.Cells[4].Style.Font = new PdfTrueTypeFont(new Font("Arial", 10f, FontStyle.Bold | FontStyle.Italic), true);
row0.Cells[4].StringFormat = new PdfStringFormat(PdfTextAlignment.Center, PdfVerticalAlignment.Middle);
row0.Cells[4].Style.BackgroundBrush = PdfBrushes.LightGreen;
row1.Cells[1].Value = "Diving International Unlimited";
row1.Cells[1].StringFormat = new PdfStringFormat(PdfTextAlignment.Center, PdfVerticalAlignment.Middle);
row1.Cells[1].ColumnSpan = 4;
Step 5: Draw the new grid and save the file, the review it.
grid.Draw(page, new PointF(0, 100));
doc.SaveToFile("result.pdf");
System.Diagnostics.Process.Start("result.pdf");
Following is the result screenshot:
