java - 如何使列填满整个表？

我创建了一个tableViewer，其中包含一个具有两列的表。事实是，两列并未填满所有表格区域，我想创建两个具有相同比例的列来填满它。

码：

TableViewer viewer = new TableViewer(createProjectConfig, SWT.MULTI | SWT.H_SCROLL| SWT.V_SCROLL | SWT.FULL_SELECTION | SWT.BORDER);
TableViewerColumn viewerColumn = new TableViewerColumn(viewer, SWT.NONE);
TableViewerColumn viewerColumn1 = new TableViewerColumn(viewer, SWT.NONE);

Table createVariablesTable = viewer.getTable();
createVariablesTable.setLayoutData(new FormData());
createVariablesTable.setHeaderVisible(true);
createVariablesTable.setLinesVisible(true);

FormData createVariablesTableData = new FormData();
createVariablesTableData.left = new FormAttachment(selectProjectPathLabel, 0, SWT.LEFT);
createVariablesTableData.top = new FormAttachment(selectProjectPathLabel, 40, SWT.TOP);
createVariablesTableData.right = new FormAttachment(selectProjectPathButton,0,SWT.RIGHT);
createVariablesTableData.bottom = new FormAttachment(createProjectConfigButton,-10,SWT.TOP);
createVariablesTable.setLayoutData(createVariablesTableData);

TableColumn column = viewerColumn.getColumn();
column.setText("${Variable}");
column.setWidth(50);//Make this fill the half of the table
column.setResizable(true);
column.setMoveable(true);

TableColumn column1 = viewerColumn1.getColumn();
column1.setText("${AAA}");
column1.setWidth(50);//Make this fill the half of the table
column1.setResizable(true);
column1.setMoveable(true);

最佳答案

您需要为表格设置表格布局。

TableLayout tableLayout = new TableLayout();
createVariablesTable.setLayout(tableLayout);

然后为每列设置列权重：

tableLayout.addColumnData(new ColumnWeightData(50));

tableLayout.addColumnData(new ColumnWeightData(50));

同时删除对column.setWidth(50)的呼叫
