Question

How can i hide the table border using iTextSharp. I am using following code to generate a file:

var document = new Document(PageSize.A4, 50, 50, 25, 25);

//         


        

Answer 1

PdfPTable table = new PdfPTable(4);
table.TotalWidth = 400f;
table.LockedWidth = true;
PdfPCell header = new PdfPCell(new Phrase("Header"));
header.Colspan = 4;
table.AddCell(header);
table.AddCell("Cell 1");
table.AddCell("Cell 2");
table.AddCell("Cell 3");
table.AddCell("Cell 4");
PdfPTable nested = new PdfPTable(1);
nested.AddCell("Nested Row 1");
nested.AddCell("Nested Row 2");
nested.AddCell("Nested Row 3");
PdfPCell nesthousing = new PdfPCell(nested);
nesthousing.Padding = 0f;
table.AddCell(nesthousing);
PdfPCell bottom = new PdfPCell(new Phrase("bottom"));
bottom.Colspan = 3;
table.AddCell(bottom);
doc.Add(table);

---

PdfPTable table = new PdfPTable(3);
table.TotalWidth = 144f;
table.LockedWidth = true;
table.HorizontalAlignment = 0;
PdfPCell left = new PdfPCell(new Paragraph("Rotated"));
left.Rotation = 90;
table.AddCell(left);
PdfPCell middle = new PdfPCell(new Paragraph("Rotated"));
middle.Rotation = -90;
table.AddCell(middle);
table.AddCell("Not Rotated");
doc.Add(table);

Although I upvoted the answer by Martijn, I want to add a clarification.

Only cells have borders in iText; tables don't have a border. Martijn's suggestion to set the border of the default cell to NO_BORDER is correct:

table.DefaultCell.Border = Rectangle.NO_BORDER;

But it won't work for the code snippet provided in the question. The properties of the default cell are only used if iText needs to create a PdfPCell instance implicitly (for instance: if you use the addCell() method passing a Phrase as parameter).

In the code snippet provided by @Brown_Dynamite, the PdfPCell objects are created explicitly. This means that you need to set the border of each of these cells to NO_BORDER.

Usually, I write a factory class to create cells. That way, I can significantly reduce the amount of code in the class that creates the table.

Answer 3

First we can set all cell borders as 0 and After assigning all cell to table we can use the following code for for only pdfptable outer border.

        PdfPCell cell = new PdfPCell();
        cell.AddElement(t);
        cell.BorderWidthBottom=1f;
        cell.BorderWidthLeft=1f;
        cell.BorderWidthTop=1f;
        cell.BorderWidthRight = 1f;
        PdfPTable t1 = new PdfPTable(1);
        t1.AddCell(cell);

Here we can add table to one cell and can set border and again add that cell to another table and we can use as per our requirement.

Answer 4

This should do the trick:

table.DefaultCell.Border = Rectangle.NO_BORDER; 

or

table.borderwidth= 0;

Answer 5

try this code

 yourtable.DefaultCell.Border = 0;

Answer 6

If your PdfPTable is nested within another PdfPTable, the nested table will show table borders. The only way to get rid of the table borders is to put the nested PdfPTable into a PdfPCell of the main PdfPTable and set the border width of that cell to 0.

iTextSharp.text.pdf.PdfPTable table = new iTextSharp.text.pdf.PdfPTable(1); //<-- Main table
table.TotalWidth = 540f;
table.LockedWidth = true;
float[] widths = new float[] { 540f };
table.SetWidths(widths);
table.HorizontalAlignment = 1; //0=Left, 1=Centre, 2=Right
table.SpacingAfter = 10;

PdfPTable bodyTable = new PdfPTable(1); //<--Nested Table
bodyTable.TotalWidth = 540f;
bodyTable.LockedWidth = true;
float[] bodyWidths = new float[] { 540f };
bodyTable.SetWidths(bodyWidths);
bodyTable.HorizontalAlignment = 0;
bodyTable.SpacingAfter = 10;
bodyTable.DefaultCell.Border = iTextSharp.text.Rectangle.NO_BORDER;

var para1 = new Paragraph("This is a long paragraph", blackNormal);
para1.SetLeading(3f, 1f);
PdfPCell bodyCell1 = new PdfPCell();
bodyCell1.AddElement(para1);
bodyCell1.Border = 0;
bodyTable.AddCell(bodyCell1);

iTextSharp.text.pdf.PdfPCell cellBody = new iTextSharp.text.pdf.PdfPCell(bodyTable);
cellBody.BorderWidth = 0; //<--- This is what sets the border for the nested table
table.AddCell(cellBody);

Took me a long time to figure this out. It works for me now.
