Spire.PDF supports to delete rows or columns from a PDF grid before drawing it onto a PDF page. This article demonstrates the detail steps of how to delete a row and a column from a PDF grid using Spire.PDF.
Detail steps:
Step 1: Create a PDF document and add a page to it.
PdfDocument doc = new PdfDocument(); PdfPageBase page = doc.Pages.Add();
Step 2: Create a PDF grid.
PdfGrid grid = new PdfGrid(); //Set cell padding grid.Style.CellPadding = new PdfPaddings(3, 3, 1, 1);
Step 3: Add 3 rows and 4 columns to the grid.
PdfGridRow row1 = grid.Rows.Add(); PdfGridRow row2 = grid.Rows.Add(); PdfGridRow row3 = grid.Rows.Add(); grid.Columns.Add(4);
Step 4: Set columns' width.
foreach (PdfGridColumn column in grid.Columns)
{
column.Width = 60f;
}
Step 5: Add values to grid cells.
for (int i = 0; i < grid.Columns.Count; i++)
{
row1.Cells[i].Value = String.Format("column{0}", i + 1);
row2.Cells[i].Value = "a";
row3.Cells[i].Value = "b";
}
Step 6: Delete the second row and the second column from the grid.
grid.Rows.RemoveAt(1); grid.Columns.RemoveAt(1);
Step 7: Draw the grid onto the page and save the file.
grid.Draw(page, new PointF(0, 20));
doc.SaveToFile("Output.pdf");
