gwtflex表问题

我使用以下代码动态创建一个flex表

for (int CurrentRow=1;CurrentRow<2;CurrentRow++)
                {
                    Label lblGettingName = new Label("Getting Name...");
                    View.getMainFlex().setWidget(CurrentRow, 0, lblGettingName);

                    Button btnViewDetails = new Button("View Details");
                    View.getMainFlex().setWidget(CurrentRow, 1, btnViewDetails);

                    Label lblGettingBid = new Label("Getting Bid...");
                    View.getMainFlex().setWidget(CurrentRow, 2, lblGettingBid);
                    View.getMainFlex().getFlexCellFormatter().setStyleName(CurrentRow, 2, "BackNormalNotBold");

                    Label lblGettingBidDesription = new Label("Getting Bid Desription...");
                    lblGettingBidDesription.setStyleName("BidDesc");
                    View.getMainFlex().setWidget(CurrentRow, 3, lblGettingBidDesription);
                    View.getMainFlex().getCellFormatter().setWidth(CurrentRow, 3, "40");
                    View.getMainFlex().getFlexCellFormatter().setStylePrimaryName(CurrentRow, 3, ".BidDesc");

                    Label lblCalculating = new Label("Calculating..");

                    Label lblCalculatingTime = new Label("Calculating Time...");
                    View.getMainFlex().setWidget(CurrentRow, 4, lblCalculatingTime);
                    View.getMainFlex().getFlexCellFormatter().setStyleName(1,4, "BackNormalNotBold");

                    TextBox textBox = new TextBox();
                    View.getMainFlex().setWidget(CurrentRow+1, 3, textBox);
                    View.getMainFlex().getCellFormatter().setWidth(CurrentRow+1, 3, "40");

                    View.getMainFlex().getFlexCellFormatter().setStyleName(CurrentRow, 0, "BackNormalNotBold");
                    View.getMainFlex().getFlexCellFormatter().setStyleName(CurrentRow, 1, "BackNormalNotBold");
                    View.getMainFlex().getFlexCellFormatter().setStyleName(CurrentRow, 2, "BackNormalNotBold");
                    View.getMainFlex().getFlexCellFormatter().setStyleName(CurrentRow+1, 3, "BackNormalNotBold");
                    View.getMainFlex().getFlexCellFormatter().setRowSpan(CurrentRow, 4, 3);
                    View.getMainFlex().getFlexCellFormatter().setRowSpan(CurrentRow, 2, 3);
                    View.getMainFlex().getFlexCellFormatter().setRowSpan(CurrentRow, 1, 3);
                    View.getMainFlex().getFlexCellFormatter().setRowSpan(CurrentRow, 0, 3);
                    View.getMainFlex().getFlexCellFormatter().setColSpan(CurrentRow+1, 3, 2);
                    View.getMainFlex().getFlexCellFormatter().setColSpan(CurrentRow, 3, 2);
                    View.getMainFlex().getFlexCellFormatter().setColSpan(CurrentRow-1, 3, 2);

                    View.getMainFlex().getCellFormatter().setHorizontalAlignment(CurrentRow, 1, HasHorizontalAlignment.ALIGN_CENTER);
                    View.getMainFlex().getCellFormatter().setVerticalAlignment(CurrentRow, 1, HasVerticalAlignment.ALIGN_MIDDLE);
                    View.getMainFlex().getCellFormatter().setVerticalAlignment(CurrentRow, 0, HasVerticalAlignment.ALIGN_MIDDLE);
                    View.getMainFlex().getCellFormatter().setHorizontalAlignment(CurrentRow, 0, HasHorizontalAlignment.ALIGN_CENTER);
                    View.getMainFlex().getCellFormatter().setHorizontalAlignment(CurrentRow, 2, HasHorizontalAlignment.ALIGN_CENTER);
                    View.getMainFlex().getCellFormatter().setHorizontalAlignment(CurrentRow+1, 3, HasHorizontalAlignment.ALIGN_CENTER);
                    View.getMainFlex().getCellFormatter().setHorizontalAlignment(CurrentRow, 3, HasHorizontalAlignment.ALIGN_CENTER);

                    Button btnPlaceBid = new Button("Bid!");
                    View.getMainFlex().setWidget(CurrentRow+2, 3, btnPlaceBid);
                    View.getMainFlex().getCellFormatter().setWidth(CurrentRow+2, 3, "20");
                    btnPlaceBid.setSize("66px", "26px");

                    ToggleButton tglbtnAutomate = new ToggleButton("Automate");
                    View.getMainFlex().setWidget(3, 4, tglbtnAutomate);
                    View.getMainFlex().getCellFormatter().setWidth(3, 4, "20");
                    tglbtnAutomate.getDownHoveringFace().setText("TurnOFF");
                    tglbtnAutomate.getUpHoveringFace().setText("TurnON");
                    tglbtnAutomate.getDownDisabledFace().setText("Enable");
                    tglbtnAutomate.setHTML("Auto:OFF");
                    tglbtnAutomate.getUpFace().setHTML("Auto:OFF");
                    tglbtnAutomate.getDownFace().setHTML("Auto:ON");
                    tglbtnAutomate.setSize("54px", "18px");
                    View.getMainFlex().getCellFormatter().setHorizontalAlignment(CurrentRow+2, 3, HasHorizontalAlignment.ALIGN_RIGHT);
                    View.getMainFlex().getCellFormatter().setHorizontalAlignment(CurrentRow-1, 4, HasHorizontalAlignment.ALIGN_CENTER);
                    View.getMainFlex().getCellFormatter().setHorizontalAlignment(CurrentRow, 4, HasHorizontalAlignment.ALIGN_CENTER);
                }
                FlexTableHelper.fixRowSpan(View.getMainFlex());

当循环只执行一次时，会生成正确的布局，但当我尝试创建多行时，布局速度下降很可能是由于setRowSpan/setColSpan方法引起的，这些方法很容易破坏布局。不使用这些方法，您可以创建复合小部件/Html并将其放置在单元格中，这样Flextable的行/列数量就会减少。

Flextable使用td的旧元素属性，如宽度、高度、对齐等。 即使在最新版本中，它也还没有适应使用CSS。例如，IE11已经完全不支持了
