iText PDF动态生成

我有一个动态生成PDF的类，，我有一个4-6列.. 在第二列描述中，一个名称是动态显示的，它有大约20-40个字符..现在我想要一致地显示行高度.. 如果任何一个描述字符超过30个字符我必须显示所有行高度相等的高度（20f）如果字符不超过并且结束低于30字符我必须显示所有行高（10f）。iText PDF动态生成

我该如何动态调整它？这里是我的代码：

mainTable.addCell (PDFUtil.getBlankLine (20f)); 
float[] colsWidth = {0.5f,3.8f,0.9f,0.9f,1.3f,0.9f,1.3f,1.4f}; 
PdfPTable itemListTab = new PdfPTable(colsWidth); 

PdfPCell slNo = PDFUtil.getTableHeaderCell(PDFUtil.S_NO, 
     PDFUtil.getBoldFont()); 
PdfPCell itmDesc = PDFUtil.getTableHeaderCell(PDFUtil.ITEM_DESC, 
     PDFUtil.getBoldFont()); 
PdfPCell loose = PDFUtil.getTableHeaderCell(PDFUtil.LOOSE_QTY, 
     PDFUtil.getBoldFont());

     PDFUtil.getBoldFont()); 
PdfPCell disc = PDFUtil.getTableHeaderCell(
     PDFUtil.ITM_DISCOUNT_PERCENT, PDFUtil.getBoldFont()); 
PdfPCell netAmt = PDFUtil.getTableHeaderCell(PDFUtil.NET_PRICE, 
     PDFUtil.getBoldFont()); 
PdfPCell amt = PDFUtil.getTableHeaderCell(PDFUtil.AMOUNT_LABEL, PDFUtil 
     .getBoldFont()); 
amt.setHorizontalAlignment(Element.ALIGN_RIGHT);

嘿家伙终于让我找到了解决这个：

mainTable.addCell(PDFUtil.getBlankLine(20f)); 
    float[] colsWidth = {0.5f,3.8f,0.9f,0.9f,1.3f,0.9f,1.3f,1.4f}; 
    PdfPTable itemListTab = new PdfPTable(colsWidth); 

    PdfPCell slNo = PDFUtil.getTableHeaderCell(PDFUtil.S_NO, 
     PDFUtil.getBoldFont()); 

    PdfPCell itmDesc = PDFUtil.getTableHeaderCell(PDFUtil.ITEM_DESC, 
     PDFUtil.getBoldFont()); 

    PdfPCell loose = PDFUtil.getTableHeaderCell(PDFUtil.LOOSE_QTY, 
     PDFUtil.getBoldFont()); 
    PdfPCell full = PDFUtil.getTableHeaderCell(PDFUtil.FULL_QTY, 
     PDFUtil.getBoldFont()); 
    PdfPCell unitPrc = PDFUtil.getTableHeaderCell(PDFUtil.QUOTED_PRICE, 
     PDFUtil.getBoldFont()); 

    PdfPCell disc = PDFUtil.getTableHeaderCell(
     PDFUtil.ITM_DISCOUNT_PERCENT, PDFUtil.getBoldFont()); 
    PdfPCell netAmt = PDFUtil.getTableHeaderCell(PDFUtil.NET_PRICE,

      .getNormalFont()))); 

    itemListTab.addCell(new PdfPCell(new Phrase(InventoryUtil.getTwoDecDigPrecisionMin(itmMstrVO.getDiscPercent()), PDFUtil 
      .getNormalFont()))); 
    itemListTab.addCell(new PdfPCell(new Phrase((InventoryUtil.getTwoDecDigPrecisionMin(itmMstrVO.getDiscUnitPrice()))+"/" +flFlagCheck, PDFUtil.getNormalFont()))); 
    itemListTab.addCell(new PdfPCell(new Phrase(InventoryUtil.getTwoDecDigPrecisionMin(itmMstrVO.getAmount()), PDFUtil 
      .getNormalFont()))); 
     } 
    } 
    } 
    PdfPCell addCell = new PdfPCell(itemListTab); 
    addCell.setBorder(0); 
    mainTable.addCell(addCell);

我已经介绍了线路长度检查和一些计算用于固定的高度。在计算高度后，我为下面的pdfpcell设置fixedheight属性。
