CODE IN CO

OATableBean table = 
                (OATableBean)webBean.findChildRecursive("LineTable");
            int numOfRowsDisplay = table.getNumberOfRowsDisplayed();
            Serializable[] param01 = { new Number(numOfRowsDisplay) };
            Class[] classType = new Class[] { Number.class, };
            am.invokeMethod("addPlanLines", param01, classType);

CODE IN AM

public void addPlanLines(Number numOfDisplay) {
        OADBTransaction tsn = this.getOADBTransaction();

        CuxPosAuditPlanLinesFullVOImpl lineVO = 
            getCuxPosAuditPlanLinesFullVO();
        Number planId = getPlanId();

        lineVO.setMaxFetchSize(0);
        if (!lineVO.isPreparedForExecution()) {
            lineVO.setWhereClause(null);
            lineVO.executeQuery();
        }

        RowSet localRowSet = lineVO.getRowSet();

        int i = 1;
        int j = numOfDisplay.intValue();
        int rangeStart = localRowSet.getRangeStart();
        int rangeSize = localRowSet.getRangeSize();
        int rowCountInRange = localRowSet.getRowCountInRange();
        int i1;
        if (rowCountInRange + i <= j)
            i1 = rowCountInRange;
        else {
            i1 = j - i;
        }
        CuxPosAuditPlanLinesFullVORowImpl row = 
            (CuxPosAuditPlanLinesFullVORowImpl)lineVO.createRow();
        if (rangeSize < i1) {
            rangeSize++;
            localRowSet.setRangeSize(rangeSize);
            localRowSet.setRangeStart(rangeStart);
        }

        row.setPlanId(planId);
        Number pk = getSequenceValue("CUX_POS_AUDIT_PLAN_LINES_S");
        row.setLineId(pk);
        row.setOrgId(new Number(tsn.getOrgId()));
        row.setOrgName(getOrgName(tsn.getOrgId()));
        localRowSet.insertRowAtRangeIndex(i1, row);
        localRowSet.setCurrentRowAtRangeIndex(i1);
    }

方法二:

/**
   * This method is for use with UI Table addRows buttons that require the
   * addition of multiple rows; given a RowIterator (such as a VO) and the
   * number of rows the caller needs to add, this method figures out where
   * the caller should start adding rows in order to comply with the BLAF
   * standard that newly added rows should go into the bottom of the current
   * table range (which is the same as the RowIterator range if things are
   * set up properly), pushing rows into the next range if necessary
   *
   * Returns: range-based (not absolute) index within the current range
   */
  public static int getStartIndexForMultiInsert(RowIterator rowIt, int numRowsToAdd)
  {
    int numRowsInRange = rowIt.getRowCountInRange();
    int rangeSize = rowIt.getRangeSize();
    int firstIndexAtWhichToAdd = 0;
    int numOpenSlotsInRange = (rangeSize - numRowsInRange);

    if (rowIt.getRangeSize() < rangeSize)
    {
      rowIt.setRangeSize(rangeSize);
    }

    if (numOpenSlotsInRange < numRowsToAdd)
    {
      firstIndexAtWhichToAdd = rangeSize - numRowsToAdd;
    }
    else
    {
      firstIndexAtWhichToAdd = numRowsInRange;
    }

    return firstIndexAtWhichToAdd;
  }

调用: 
 int indexForRowInserts = getStartIndexForMultiInsert(vo, 1);
  vo.insertRowAtRangeIndex(indexForRowInserts,row);

方法三：

这种方法有点小问题：

仅仅在第一页有效，应该可以再修改修改，懒得改了

calculVO.insertRow(row);   
 int fetched = calculVO.getFetchedRowCount();
 fetched = fetched > 9 ? 9 : fetched;
 if (fetched > 0)
 {
   int current = fetched % 10;
   if (current == 0)
   {
     fetched = 9;
   } else
   {
     fetched = current > 9 ? 9 : current;
   }
 }
 calculVO.insertRowAtRangeIndex(fetched, row);
