you asking itextsharp create 12 column table using 4 of columns, 3 cells 1 cell spanned 2 columns.

dim table new pdfptable(12) 

related, have glitch or copy , paste error because keep settings colspan on same variable on , over.

celldate.colspan = 2 ''//this in code 3 times 

itextsharp ignores incomplete rows default , since have single row , isn't complete have 0 content.

you can change column count in constructor you're going use:

dim table new pdfptable(4) 

if assumption typo correct want when fixed:

dim table new pdfptable(6) 

if you've got valid reason not use same number of columns specify can use right before adding table document "fill in blanks".

table.completerow()
