iText PDF动态生成

我有一个动态生成PDF的课程， 在那我有4-6列.. 在第二列描述中，动态显示项目名称， 它有大约20-40个字符..现在我想要一致地显示行高... 如果任何一个描述字符超过30个字符，我必须将所有行高度显示为相等的高度（20f） 如果角色没有超过并且低于30个字符，我必须将所有行高度显示为（10f）。

如何动态对齐？ 这是我的代码：

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());
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,
        PDFUtil.getBoldFont());
PdfPCell amt = PDFUtil.getTableHeaderCell(PDFUtil.AMOUNT_LABEL, PDFUtil
        .getBoldFont());
amt.setHorizontalAlignment(Element.ALIGN_RIGHT);
itemListTab.addCell(slNo);
itemListTab.addCell(itmDesc);
itemListTab.addCell(full);
itemListTab.addCell(loose);
itemListTab.addCell(unitPrc);
itemListTab.addCell(disc);
itemListTab.addCell(netAmt);
itemListTab.addCell(amt);
ArrayList aList = vendPOVO.getItemList();
if (aList != null)
{
    Object[] iList = aList.toArray();
    Arrays.sort(iList, new ItemSNoComparator(aList));
    int len = iList.length;
    InventoryLogger.logDebug("After sorting the item list by SNo");
    InventoryLogger.logDebug("length"+len);
    for (int i = 0; i < len; i++)
    {
        InventoryLogger.logDebug("inside for");
        ItemMasterVO itmMstrVO = (ItemMasterVO) iList[i];
        if (InventoryConstants.TRUE.equals(itmMstrVO
            .getVendPurOrdInd()))
        {
            String ctry = " ";
            InventoryLogger.logDebug ("Country of origin"+itmMstrVO.getCtryOfOrigin());
            if(itmMstrVO.getCtryOfOrigin() != null)
            {
                ctry =  InventoryUtil.getStaticElementDescription(
                        itmMstrVO.getCtryOfOrigin(),InventoryConstants.STATIC_ELE_CTRY);
            }
            String uomDesc = "";
            String looseUomTemp = "";
            if(itmMstrVO.getUomDesc().matches(InventoryConstants.UOM_KGGM) )
            {
                uomDesc = "1 KG ";
                looseUomTemp = "KG";

            String flFlagCheck = "";

            }
            else
            {
                flFlagCheck = itmMstrVO.getLooseUOM();
            }

            itemListTab.addCell(new PdfPCell(new Phrase(itmMstrVO
                .getCusQuoSerialNo(), PDFUtil
                .getNormalFont())));

嘿伙计终于找到了解决方案：

  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,

        }

我已经介绍了线长检查和一些固定高度的计算。计算高度后，我为下面的fixedheight设置了pdfpcell属性。
