SWT StyledCellLabelProvider崩溃表格外观和选择

Question

在使用StyledCellLabelProvider之后，我的表格看起来有问题。

以下是快速代码段代码：

        table = tableViewer.getTable();
        table.setHeaderVisible(true);
        table.setLinesVisible(false);

        TableViewerColumn tableViewerColumn = new TableViewerColumn(tableViewer, SWT.NONE);
        TableColumn tableColumn = tableViewerColumn.getColumn();
        layout.setColumnData(tableColumn, new ColumnWeightData(2, ColumnWeightData.MINIMUM_WIDTH, true));

        initModel();
        initListener();
        return container;
    }

    private void initListener() {
        table.addListener(SWT.MouseDown, new Listener() {

            @Override
            public void handleEvent(Event event) {
                table.setEnabled(false);
            }

    private void initModel() {
        List<SampleModel> sampleModelElements = new ArrayList<SampleModel>();
        sampleModelElements.add(new SampleModel("test1_1", "test1_2"));
        sampleModelElements.add(new SampleModel("test2_1", "test2_2"));
        sampleModelElements.add(new SampleModel("test3_1", "test3_2"));
        tableViewer.setInput(sampleModelElements);
    }

    @Override

        return new CoolBarManager(style);
    }

    @Override
    protected StatusLineManager createStatusLineManager() {
        return new StatusLineManager();
    }

    public static void main(String args[]) {
        try {
            SwtIssueWithTableSelectionAndBorders window = new SwtIssueWithTableSelectionAndBorders();
            window.setBlockOnOpen(true);
            window.open();
            Display.getCurrent().dispose();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    @Override

        super.configureShell(newShell);
        newShell.setText("TableApp");
    }

    @Override
    protected Point getInitialSize() {
        return new Point(400,300);
    }

    private class SampleLabelProvider extends LabelProvider implements ITableLabelProvider {
        public Image getColumnImage(Object element, int columnIndex) {
            return null;
        }
        public String getColumnText(Object element, int columnIndex) {
            SampleModel sampleModel = (SampleModel) element;
            String result = "";
            switch(columnIndex){
                case 0:
                    result = sampleModel.getTest1();
                    break;
                case 1:
                    result = sampleModel.getTest2();
                    break;
            }
            return result;
        }
    }
    private class ContentProvider implements IStructuredContentProvider {
        public Object[] getElements(Object inputElement) {
            List<SampleModel> sampleModelElements = (List<SampleModel>)inputElement;
            return sampleModelElements.toArray();
        }
        public void dispose() {
        }
        public void inputChanged(Viewer viewer, Object oldInput, Object newInput) {
        }
    }

    private class SampleModel {
        private String test1;
        private String test2;

        public SampleModel(String test1, String test2) {
            super();
            this.test1 = test1;
            this.test2 = test2;
        }

        public String getTest1() {
            return test1;
        }

        public String getTest2() {
            return test2;
        }
   }
}

当我运行此代码时，一切都按预期工作。 表在列之间有分隔符（因为table.setLinesVisible（false）而不在行之间）：

当我点击一行时，我有可见的禁用选择：

当我取消注释行时出现问题：

tableViewerColumn.setLabelProvider（cellLabelProvider）;

比列之间没有分隔符：

如果我在一行上按下鼠标按钮，则禁用表中没有选择：

当它被禁用并且使用StyledCellLabelProvider时，有没有办法以某种方式将选择带回到表中？
