Swinghacks——JTable單擊表頭選中列

jtable預設單擊表頭是沒有什麼反應的，對於使用過excel的人來說會很失望

要讓單擊表頭就選中該列也很簡單，直接上代碼

import javax.swing.*;import javax.swing.table.*;import java.awt.event.*;public class ColumnSelectableJTable extends JTable {    public ColumnSelectableJTable (Object[][] items, Object[] headers) {        super (items, headers);        //設定列選擇模式        setColumnSelectionAllowed (true);        setRowSelectionAllowed (false);        final JTableHeader header = getTableHeader();        //表頭增加監聽        header.addMouseListener (new MouseAdapter() {                public void mouseReleased (MouseEvent e) {                    if (! e.isShiftDown())                        clearSelection();                    //擷取點擊的列索引                    int pick = header.columnAtPoint(e.getPoint());                    //設定選擇模型                    addColumnSelectionInterval (pick, pick);                }            });            }}
