Adding Columns

The TableColumn class represents a column in the table. You create a column with a parent table, a style, and optionally an index. If you don't specify an index, the column assumes the next available zero-based index. public TableColumn(Table parent, int style) public TableColumn(Table parent, int style, int index) The supported styles all specify the alignment for the column's contents: SWT.LEFT for left alignment, SWT.CENTER for center alignment, and SWT.RIGHT for right alignment. You should specify only one of these; You can change alignment after construction using the setAlignment() method. Alignment defaults to left and affects all rows in the column. import org.eclipse.swt.SWT; import org.eclipse.swt.widgets.Display; import org.eclipse.swt.widgets.Shell; import org.eclipse.swt.widgets.Table; import org.eclipse.swt.widgets.TableColumn; import org.eclipse.swt.widgets.TableItem; public class TableColumnAdding {   public static void main(String[] args) {     Display display = new Display();     Shell shell = new Shell(display);     Table table = new Table(shell, SWT.MULTI | SWT.BORDER | SWT.FULL_SELECTION);     table.setLinesVisible(true);     table.setHeaderVisible(true);     String[] titles = { " ", "C", "!", "Description"};     for (int i = 0; i < titles.length; i++) {       TableColumn column = new TableColumn(table, SWT.RIGHT);       column.setText(titles[i]);     }     for (int i = 0; i < 10; i++) {       TableItem item = new TableItem(table, SWT.NONE);       item.setText(0, "x");       item.setText(1, "y");       item.setText(2, "!");       item.setText(3, "d");     }     for (int i=0; i<titles.length; i++) {       table.getColumn (i).pack ();     }               table.setSize(table.computeSize(SWT.DEFAULT, 200));     shell.pack();     shell.open();     while (!shell.isDisposed()) {       if (!display.readAndDispatch())         display.sleep();     }     display.dispose();   } }
