Question

gwt-incubator的ScrollTable我遇到了一个小问题。似乎ScrollTable已呈现，但它添加了“overflow：hidden”样式，这会使其对用户隐藏。

我正在使用GWT 2.0和UiBinder。我用来创建ScrollTable的代码是：

 @UiFactory ScrollTable createCompaniesTable() {
  FixedWidthGrid dataTable = createDataTable();
  FixedWidthFlexTable headerTable = createHeaderTable();

  return new ScrollTable(dataTable, headerTable);
 }

 private FixedWidthFlexTable createHeaderTable() {
  // Create a new table
  FixedWidthFlexTable headerTable = new FixedWidthFlexTable();
  FlexTable.FlexCellFormatter formatter = headerTable.getFlexCellFormatter();

  // Level 1 headers
  headerTable.setHTML(0, 0, "<b>Student Profiles</b>");
  formatter.setColSpan(0, 0, 6);
  formatter.setHorizontalAlignment(0, 0, HasHorizontalAlignment.ALIGN_CENTER);

  // Level 2 headers
  headerTable.setHTML(1, 0, "<b>General</b>");
  formatter.setColSpan(1, 0, 4);
  formatter.setHorizontalAlignment(1, 0, HasHorizontalAlignment.ALIGN_CENTER);
  headerTable.setHTML(1, 1, "<b>Student ID</b>");
  formatter.setRowSpan(1, 1, 2);
  formatter.setHorizontalAlignment(1, 1, HasHorizontalAlignment.ALIGN_CENTER);
  headerTable.setHTML(1, 2, "<b>GPA</b>");
  formatter.setRowSpan(1, 2, 2);
  formatter.setHorizontalAlignment(1, 2, HasHorizontalAlignment.ALIGN_CENTER);

  // Level 3 headers
  headerTable.setHTML(2, 0, "Last Name");
  formatter.setHorizontalAlignment(2, 0, HasHorizontalAlignment.ALIGN_CENTER);
  headerTable.setHTML(2, 1, "First Name");
  formatter.setHorizontalAlignment(2, 1, HasHorizontalAlignment.ALIGN_CENTER);
  headerTable.setHTML(2, 2, "Age");
  formatter.setHorizontalAlignment(2, 2, HasHorizontalAlignment.ALIGN_CENTER);
  headerTable.setHTML(2, 3, "Hometown");
  formatter.setHorizontalAlignment(3, 3, HasHorizontalAlignment.ALIGN_CENTER);

  return headerTable;
 }

 private FixedWidthGrid createDataTable() {
  // Create a new table
        FixedWidthGrid dataTable = new FixedWidthGrid(100, 10);

        // Set some options in the data table
        dataTable.setSelectionPolicy(SelectionGrid.SelectionPolicy.MULTI_ROW);
  dataTable.insertRow(0);
  dataTable.setHTML(0, 0, "<b>Hello, World!</b>");


        // Return the data table
        return dataTable;
 }

它与gwt-incubator的文档大致相同。我缺少什么？

我忘了提及，我将ResizePolicy设置为“BOTH”。我把它取下后，桌子出现了。

要使滚动功能起作用，必须将高度CSS属性添加到ScrollTable。：）

gwt-incubator ScrollTable使用overflow：hidden呈现
