我修改了SWT代码段，以显示如何对具有不同数据类型的列进行排序。
import java.text.SimpleDateFormat;import java.util.Arrays;import java.util.Comparator;import java.util.Date;import org.eclipse.swt.SWT;import org.eclipse.swt.layout.FillLayout;import org.eclipse.swt.widgets.Display;import org.eclipse.swt.widgets.Event;import org.eclipse.swt.widgets.Listener;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 SortTable { private TableRow rows[] = new TableRow[] { new TableRow(1, "aaa", new Date(1363784269000L)), new TableRow(2, "abc", new Date(1367784269000L)), new TableRow(3, "efc", new Date(1363584269000L)), new TableRow(4, "ccc", new Date(1363734269000L)), }; private Table table; private TableColumn intColumn; private TableColumn strColumn; private TableColumn dateColumn; public SortTable() { Display display = new Display(); Shell shell = new Shell(display); shell.setLayout(new FillLayout()); table = new Table(shell, SWT.BORDER); table.setHeaderVisible(true); intColumn = new TableColumn(table, SWT.NONE); intColumn.setText("int"); intColumn.setWidth(50); strColumn = new TableColumn(table, SWT.NONE); strColumn.setText("string"); strColumn.setWidth(50); dateColumn = new TableColumn(table, SWT.NONE); dateColumn.setText("date"); dateColumn.setWidth(100); updateTable(); Listener sortListener = new Listener() { public void handleEvent(Event e) { TableColumn column = (TableColumn) e.widget; if (column == intColumn) Arrays.sort(rows, BY_VAL); if (column == strColumn) Arrays.sort(rows, BY_STR); if (column == dateColumn) Arrays.sort(rows, BY_DATE); table.setSortColumn(column); updateTable(); } }; intColumn.addListener(SWT.Selection, sortListener); strColumn.addListener(SWT.Selection, sortListener); dateColumn.addListener(SWT.Selection, sortListener); shell.setSize(shell.computeSize(SWT.DEFAULT, SWT.DEFAULT).x, 300); shell.open(); while (!shell.isDisposed()) { if (!display.readAndDispatch()) display.sleep(); } display.dispose(); } private void updateTable() { table.removeAll(); for (TableRow row : rows) { TableItem item = new TableItem(table, SWT.NONE); item.setText(row.asString()); } } public final Comparator<TableRow> BY_VAL = new Comparator<TableRow>() { @Override public int compare(TableRow o1, TableRow o2) { if (o1.val < o2.val) return -1; if (o1.val > o2.val) return 1; return 0; } }; public final Comparator<TableRow> BY_STR = new Comparator<TableRow>() { @Override public int compare(TableRow o1, TableRow o2) { return o1.str.compareTo(o2.str); } }; public final Comparator<TableRow> BY_DATE = new Comparator<TableRow>() { @Override public int compare(TableRow o1, TableRow o2) { return o1.date.compareTo(o2.date); } }; private class TableRow { private int val; private String str; private Date date; private SimpleDateFormat format = new SimpleDateFormat(); public TableRow(int val, String str, Date date) { this.val = val; this.str = str; this.date = date; } public String[] asString() { return new String[] {Integer.toString(val), str, format.format(date)}; } } public static void main(String[] args) { new SortTable(); }}总结一下， 这完全取决于程序员如何对表中的列进行排序，因为表无论它们的含义是什么，总是只需要一行String数组。
