I am using the opensource <http://itextpdf.com/> , to create some pdf . 

I could create a table , but width of all column are same , I need to change the width of the particular column .

```
PdfPTable table = new PdfPTable(6);
Phrase tablePhrse = new Phrase("Sl n0", normalFontBold);
    PdfPCell c1 = new PdfPCell(tablePhrse);
    c1.setHorizontalAlignment(Element.ALIGN_CENTER);
    table.addCell(c1);

```

I could not find any method to set the width of the column , pls suggest some way to do achieve this ..
