var pdfDoc = new Document(PageSize.A3, 10f, 10f, 10f, 0f);
System.IO.MemoryStream mStream = new System.IO.MemoryStream();
PdfWriter writer = PdfWriter.GetInstance(pdfDoc, mStream);
PdfPageEventHelper pageEventHelper = new PdfPageEventHelper();
writer.PageEvent = pageEventHelper;
HeaderFooter header = new HeaderFooter(new Phrase("Schedule report" + DateTime.Now.ToString("dd/MMM/yyyy hh:mm tt") + ""), false);
header.BackgroundColor = new iTextSharp.text.Color(System.Drawing.ColorTranslator.FromHtml("#62e456"));
// Remove the border that is set by default
header.Border = iTextSharp.text.Rectangle.TITLE;
// Align the text: 0 is left, 1 center and 2 right.
header.Alignment = Element.ALIGN_CENTER;
pdfDoc.Header = header;
// Header.
pdfDoc.Open();
string Connectionstring = ConfigurationManager.ConnectionStrings["SPCFConnectionString"].ConnectionString;
SqlConnection cn = new SqlConnection(Connectionstring);
cn.Open();
try

if (ddl_clntsearch.SelectedValue.ToString() == "")

compgrp = "All";

else

compgrp = ddl_clntsearch.SelectedValue.ToString();

string querylist = new string

"exec [SP0480_05] '" + compgrp +"','" + txt_mobnum.Text +"','"+txt_searchdate.Text+"','" + ddl_status.SelectedValue.ToString() +"'",

;

string Headers = new string

"Date"," Name","Shift time","User","Remarks","Amount","Signature"
;

foreach (string query in querylist)

iTextSharp.text.Table pdfTableheader = new iTextSharp.text.Table(7, 1);
pdfTableheader.BorderWidth = 1; pdfTableheader.Width = 100; pdfTableheader.Spacing = 1;
//pdfTableheader.Padding = 1;
foreach (string items in Headers)

Cell cellCols = new Cell();
Chunk chunkCols = new Chunk();
cellCols.BackgroundColor = new iTextSharp.text.Color(System.Drawing.ColorTranslator.FromHtml("#62e05e"));
iTextSharp.text.Font ColFont = FontFactory.GetFont(FontFactory.TIMES_ROMAN, 12, iTextSharp.text.Font.BOLD, iTextSharp.text.Color.BLACK);
//if (items == "Name")

//
//else

cellCols.Add(chunkCols);
pdfTableheader.AddCell(cellCols);

pdfDoc.Add(pdfTableheader);
SqlCommand cmd = new SqlCommand(query, cn);
cmd.CommandTimeout = 30;
cmd.CommandType = CommandType.Text;
SqlDataReader dr = cmd.ExecuteReader();
DataTable dataTable = new DataTable();
dataTable.Load(dr);
object array = new object[dataTable.Columns.Count];

//dataTable.Rows.Add(array);

int rows = dataTable.Rows.Count;
iTextSharp.text.Table pdfTable = new iTextSharp.text.Table(cols, rows);
pdfTable.BorderWidth = 1; pdfTable.Width = 100; pdfTable.Spacing = 2;
//pdfTable.Padding = 1;

//creating table data (actual result)

for (int k = 0; k <= rows - 1; k++)

for (int j = 0; j < cols; j++)



Cell cellRows = new Cell();
//if (k % 2 == 0)
cellRows.BackgroundColor = new iTextSharp.text.Color(System.Drawing.ColorTranslator.FromHtml("#ffffff"));

pdfTable.AddCell(cellRows);



pdfDoc.Add(pdfTable);


catch (Exception exc)




//creating table headers
cn.Close();
pdfDoc.Close();

Response.ContentType = "application/pdf";

Response.BinaryWrite(mStream.ToArray());

You should set the width of the columns. And you can do that by applying them to the table object. For example:

float widths = new float 1f, 2f ; //relative col widths in proportions - 1/3 and 2/3
table.SetWidths(widths);

Hope to help, my friend!
