Swing JTABLE设置表头行高

不知道你在讲什么，请贴出代码，setRowHeight()方法本来就是对表格行起作用，你要的是Excel的效果吧，设置某一行作为tableHeader并设置它的样式。这个可以做但是有点麻烦，如果你是这个需求请贴代码。

//创建table

private String[] columnNames=

private Object[][] rowData=new Object[0][4]

private DefaultTableModel tableModel=new DefaultTableModel(rowData,columnNames)

private JTable jTable=new JTable(tableModel)

//设置居中

DefaultTableCellRenderer r = new DefaultTableCellRenderer()

r.setHorizontalAlignment(JLabel.CENTER)

jTable.setDefaultRenderer(Object.class, r)

在netbeans调试运行过啦，改动如下：

（1）最后一句jp7.add(jtable)改成jp0.add(jsp)

(2)你这里JTable jtable = new JTable(new String[][] {

{"哈","飞","飞","飞","我"," 的","爱情"}，{"哈","飞","飞","飞","我"," 的","爱情"}

},

new String[] { "书名", "价格", "出版时间", "入库时间","作家","入库数","书类别" }

欠一半括号，我看不太懂，暂且改成JTable jtable = new JTable(new String[][] {

{"哈","飞","飞","飞","我"," 的","爱情"}，{"哈","飞","飞","飞","我"," 的","爱情"}

},

new String[] { "书名", "价格", "出版时间", "入库时间","作家","入库数","书类别" }）

（3）B ab = new B()应该加，ab.setVisible(true)

(4)这点只是建议．你里面大量使用的jPassordField可改用jTextField
