如何在 iTextpdf 中设置表格的行位置和宽度?这里我需要如何设置每个单元格的位置以及如何在 itextpdf 中设置行间距

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;
