JTable 设置表头，列宽后，鼠标调整表头会导致表头显示异常

[小带鱼]

做了个表格，JTable,用了以下三句核心代码

this.table.setAutoResizeMode(JTable.AUTO_RESIZE_OFF);
this.table.getTableHeader().setPreferredSize(new Dimension(this.table.getTableHeader().getPreferredSize().width,50));
this.table.setRowHeight(40);

发现，当把某一列的边拉拽到窗口外，再滚动滚动条到表格右侧，会发现表格内部表头显示异常。
正常情况如下：


把H列和I列之间的边，用鼠标拉到右边窗口外面去：

然后把滚动条滚到最后面后，发现表头显示异常了



完整代码如下：

import java.awt.BorderLayout;
import java.awt.Container;
import java.awt.Dimension;
import java.awt.Font;

import javax.swing.JFrame;
import javax.swing.JScrollPane;
import javax.swing.JTable;
import javax.swing.table.DefaultTableModel;
import javax.swing.table.TableModel;

public class TableInsertTest extends JFrame {
	private JTable table = new JTable();

	public TableInsertTest() {
		TableModel dataModel = new DefaultTableModel() {
			public int getColumnCount() {	return 15;	}
			public int getRowCount() {return 10;}
			public Object getValueAt(int row, int column) {return row * column;}
		};
		this.table = new JTable(dataModel);
		this.table.setAutoResizeMode(JTable.AUTO_RESIZE_OFF);
		this.table.getTableHeader().setPreferredSize(new Dimension(this.table.getTableHeader().getPreferredSize().width,50));
		this.table.setRowHeight(40);
		this.table.setFont(new Font("宋体",0,16));
		this.table.updateUI();
		JScrollPane scrollpane = new JScrollPane(this.table);
		Container contentPane = this.getContentPane();
		contentPane.setLayout(new BorderLayout());
		contentPane.add(scrollpane, BorderLayout.CENTER);
	}

	public static void main(String[] args) {
		TableInsertTest frame = new TableInsertTest();
		frame.setVisible(true);
		frame.setSize(800, 600);
		frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
	}
}
