asp.net - How to split columns in itextsharp? -

i have 200 columns.i want set 50 columns in 1 page,total 4 page.i used

doc.newpage()  

but not affect in page?how can split 200 column 50 in 4 pages.now looks like

there different ways this.

the first way explained in answer question what's easy print "first right, down"?

in tabletemplate example, write full table pdftemplate bigger single page:

pdfptable table = new pdfptable(15); table.settotalwidth(1500); pdfpcell cell; (int r = 'a'; r <= 'z'; r++) {     (int c = 1; c <= 15; c++) {         cell = new pdfpcell();         cell.setfixedheight(50);         cell.addelement(new paragraph(string.valueof((char) r) + string.valueof(c)));         table.addcell(cell);     } } pdfcontentbyte canvas = writer.getdirectcontent(); pdftemplate tabletemplate = canvas.createtemplate(1500, 1300); table.writeselectedrows(0, -1, 0, 1300, tabletemplate); 

once table completed, can distribute tabletemplate object on different pages:

for (int j = 0; j < 1500; j += 500) {     (int = 1300; > 0; -= 650) {         clip = canvas.createtemplate(500, 650);         clip.addtemplate(tabletemplate, -j, 650 - i);         canvas.addtemplate(clip, 36, 156);         document.newpage();     } } 

if want do, question duplicate of itext -- what's easy print "first right, down"

the second way use writeselectedrows() method. in case, question duplicate of auto split columns using itextsharp , itextsharp: adjust 2 elements on 1 page

the zhang example second edition of itext in action shows how method works:

pdfcontentbyte canvas = writer.getdirectcontent(); // draw first 2 columns on 1 page table.writeselectedrows(0, 2, 0, -1, 236, 806, canvas); document.newpage(); // draw remaining 2 columns on next page table.writeselectedrows(2, -1, 0, -1, 36, 806, canvas); 

the first time, use writeselectedrows, draw column 0 2 (not included) , row 0 total number of rows on page. second time, draw columns, starting column 2, , rows.

the third way adapt size of page size of table. explained in answer question how define page size based on content?
