I create cells from the list size and trying to set width fist 1 only number 2nd is name and next others will be only number which means i need 2nd line more spaced and others are same width. Sorry my english

I asked this question for you on one of our partnered Discords (Awit), and they mentioned taking a look at this: http://javadox.com/com.lowagie/itext/4.2.0/com/lowagie/text/pdf/PdfPTable.html#setTotalWidth(float)

public void setTotalWidth(float totalWidth)

(Parameters:totalWidth - the full width of the table).
Will set table width.

This example isnt for Java, but covers a lot of the same iText concepts

PdfPTable table = new PdfPTable(3);
PdfPCell cell = new PdfPCell(new Phrase("Header spanning 3 columns"));
cell.Colspan = 3;
cell.HorizontalAlignment = 1; //0=Left, 1=Centre, 2=Right
table.AddCell(cell);
table.AddCell("Col 1 Row 1");
table.AddCell("Col 2 Row 1");
table.AddCell("Col 3 Row 1");
table.AddCell("Col 1 Row 2");
table.AddCell("Col 2 Row 2");
table.AddCell("Col 3 Row 2");
doc.Add(table);

Here is an example I found online for iText Sharp

What version of iText are you using ??

setRowHeight(int row, int rowHeight): sets the height (in pixels) for an individual row.

Use this method:

public static void setColumnWidths(JTable table, int... widths) {

    TableColumnModel columnModel = table.getColumnModel();

    for (int i = 0; i < widths.length; i++) {

        if (i < columnModel.getColumnCount()) {

            columnModel.getColumn(i).setMaxWidth(widths);

        }

        else break;

    }

Or extend the JTable class:

public class Table extends JTable {

    public void setColumnWidths(int... widths) {

        for (int i = 0; i < widths.length; i++) {

            if (i < columnModel.getColumnCount()) {

                columnModel.getColumn(i).setMaxWidth(widths);

            }

            else break;

        }

    }

}

And then:

table.setColumnWidths(30, 150, 100, 100);

I have edited your post to make your code more understandable. 🙂
