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);
