    <p>I didn't find a clean solution. I will explain you what I have done so far. I have modified the code that I have posted. I use <code>TableViewerColumn</code> instead of <code>TableColumn</code>.</p> <p>Class FileTableView:</p> <pre class="lang-java prettyprint-override"><code>public class FileTableView extends ViewPart implements ISelectionListener{ private TableViewer tableViewer; private boolean cellEditable = false; private FirstColumnEditingSupport obj; public FileTableView() { super(); } @Override public void createPartControl(Composite parent) { //initialization of the table viewer tableViewer = new TableViewer(parent, SWT.BORDER | SWT.FULL_SELECTION | SWT.V_SCROLL | SWT.MULTI); //SWT.MULTI - for multiple selection; SWT.FULL_SELECTION - for selection of an entire row tableViewer.setContentProvider(new FileTableContentProvider()); //it is not necessary to add a label provider for the table viewer because we will set a label provider for every column of the table //tableViewer.setLabelProvider(new FileTableLabelProvider()); //extract the table widget of the table viewer final Table table = tableViewer.getTable(); //make the header of the table visible table.setHeaderVisible(true); //hide the lines of the table table.setLinesVisible(false); //create the columns of the table createColumns(parent, tableViewer); //set the sorter to the table viewer tableComparator = new TableViewerComparator(); tableViewer.setComparator(tableComparator); //from within the implementation of any view or editor /* * getSite() - Returns the site for this workbench part (a workbench part can be a view (IViewPart) or an editor (IEditorPart)) * this view is a selection provider;

This part is not working quite well, because after you press the rename menu button, you can't see that the editing mode is enabled. After you click on the table line, the editing mode is activated. Also, the editing mode is enabled for all the table lines and I wanted to be enabled only for the selected one. For this problem I haven't got a solution.</li> <li><p>after you finish typing the new name of the file, and change the selection (click on a different table line), the editing mode is disabled:</p> <pre class="lang-java prettyprint-override"><code>tableViewer.addSelectionChangedListener(new ISelectionChangedListener(){ public void selectionChanged(SelectionChangedEvent event){ setCellEditable(false); } }); </code></pre></li> </ul> <p>I hope my solution can help you.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
