問題循環爲cicle

Question

與我的代碼，我告訴你上面，我得到的行項目（請參閱圖片）姓名：1名稱：2名稱：3，而我希望這個項目留在相同的（第一）專欄... 誰能幫幫我？

PdfPCell cell; 
PdfPTable table = new PdfPTable(3); 

cell = new PdfPCell(new Phrase("Item Name")); 
cell.setHorizontalAlignment(com.lowagie.text.Element.ALIGN_LEFT); 
cell.setBorder(Rectangle.NO_BORDER); 
table.addCell(cell); 

cell = new PdfPCell(new Phrase("Quantità")); 
cell.setHorizontalAlignment(com.lowagie.text.Element.ALIGN_CENTER); 
cell.setBorder(Rectangle.NO_BORDER); 
table.addCell(cell); 

cell = new PdfPCell(new Phrase("€")); 
cell.setHorizontalAlignment(com.lowagie.text.Element.ALIGN_RIGHT); 
cell.setBorder(Rectangle.NO_BORDER); 
table.addCell(cell); 
table.setHeaderRows(1); 

for (int i=1;i<5;i++) { 
    table.addCell("Name:" + i); 
    cell.setBorder(Rectangle.NO_BORDER); 
} 

Answer 1

我相信你可以使用合併單元格像這樣：

PdfPCell cell; 
PdfPTable table = new PdfPTable(3); 

cell = new PdfPCell(new Phrase("Item Name")); 
cell.setHorizontalAlignment(com.lowagie.text.Element.ALIGN_LEFT); 
cell.setBorder(Rectangle.NO_BORDER); 
table.addCell(cell); 

cell = new PdfPCell(new Phrase("Quantità")); 
cell.setHorizontalAlignment(com.lowagie.text.Element.ALIGN_CENTER); 
cell.setBorder(Rectangle.NO_BORDER); 
table.addCell(cell); 

cell = new PdfPCell(new Phrase("€")); 
cell.setHorizontalAlignment(com.lowagie.text.Element.ALIGN_RIGHT); 
cell.setBorder(Rectangle.NO_BORDER); 
table.addCell(cell); 
table.setHeaderRows(1); 

for (int i=1;i<5;i++) { 
    // we add a cell with colspan 3 
    cell = new PdfPCell(new Phrase("Name:" + i)); 
    cell.setColspan(3); 
    cell.setBorder(Rectangle.NO_BORDER); 
    table.addCell(cell); 
}
