我想使用itextpdf動態設置表行的高度

Question

如何在iTextpdf中設置表的行位置和寬度？這里我需要如何設置每個單元格的位置以及如何在itextpdf中設置行間距

testTable11_close_right.getDefaultCell().setBorder(0);
        testTable11_close_right.getDefaultCell().setPadding(0);                 
        testTable11_close_right.addCell(aarr2);
        testTable11_close_right.addCell(s6);


            testTable111.addCell(single_tender_id);
            testTable111.addCell(s2);
            testTable111.addCell(s3);
            testTable111.addCell(testTable11_close_right);

            PdfPCell cell7 = new PdfPCell();
            PdfPTable testTable_dept= new PdfPTable(1);
            testTable_dept.setWidthPercentage(100);
            testTable_dept.getDefaultCell().setPaddingTop(0);
            testTable_dept.getDefaultCell().setHorizontalAlignment(Element.ALIGN_CENTER);
            testTable_dept.addCell(new Phrase(""+temp_department_name,myBoldFont1));                        
            cell7.addElement(testTable_dept);
            cell7.setBackgroundColor(BaseColor.BLACK);
            cell7.setHorizontalAlignment(Element.ALIGN_CENTER);


            table_odd1.addCell(cell7);                      
            table_odd1.addCell(testTable111); 
            table_odd.addCell(table_odd1);    

            return  table_odd;
