我已经设置了JTable并使其包含18列。最初，当它是13列时，它很好地适合JTable并且没有撕裂。但是，一旦我使其包含18个表并将autoresize设置为off，当我使用水平滚动条尝试滚动其他列时，JTable的撕裂开始发生，如下图所示：
Netbeans也开始给我很多这样的错误消息：

Why is this so? Are there any solution to this problem? Thanks!
So sorry! Here are the code used to initialize the table.Hope it will be useful!
jp.setLayout(new BorderLayout());
JTable jt = new JTable(data, column);// data and columns are just 2D and 1D String arrays each
JTableHeader th = jt.getTableHeader();
th.setBackground(java.awt.Color.pink);
th.setEnabled(true);
jt.setTableHeader(th);
jt.setEnabled(false);
jp.add(jt, BorderLayout.CENTER);
JScrollPane scrollPane = new JScrollPane(jt, JScrollPane.VERTICAL_SCROLLBAR_ALWAYS, JScrollPane.HORIZONTAL_SCROLLBAR_AS_NEEDED);
jt.setAutoResizeMode(JTable.AUTO_RESIZE_OFF);
scrollPane.setEnabled(false);
jp.add(scrollPane, BorderLayout.CENTER);
最佳答案
我认为您声明的列比数据数组中的列多。
此代码示例完全重现了您的问题：
import javax.swing.JFrame;
import javax.swing.JScrollPane;
import javax.swing.JTable;
import javax.swing.SwingUtilities;
public class TestTable {
public JFrame f;
private JTable table;
public static void main(String[] args) {
SwingUtilities.invokeLater(new Runnable() {
@Override
public void run() {
new TestTable().initUI();
}
});
}
protected void initUI() {
String[][] data = new String[1][1];
data[0] = new String[] { "hello" };
String[] columns = new String[] { "Column-1", "Column-2" };
table = new JTable(data, columns);
f = new JFrame();
f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
f.setSize(300, 300);
f.setLocationRelativeTo(null);
f.add(new JScrollPane(table));
f.setVisible(true);
}
}
解决方案当然是使数据中的列数与声明的列数匹配。并且您应确保使用正确数量的“列”初始化数据数组的每个“行”。
例如，您可能有以下内容：
String[][] data = new String[1][18];
data[0] = new String[15]; // <-- This will cause some problems
现在，我建议使用数组以外的其他数据结构，因为它不是非常灵活，并且它们往往难以维护。一个简单的解决方案是拥有一些“ Model”类并创建自己的TableModel，如下所示：
import java.util.List;
import java.util.Random;
import java.util.Vector;
import javax.swing.JFrame;
import javax.swing.JScrollPane;
import javax.swing.JTable;
import javax.swing.SwingUtilities;
import javax.swing.table.AbstractTableModel;
public class TestTable {
public JFrame f;
private JTable table;
public class ModelObject {
private String column0; // Consider using something more explicit than column0,1,...
private String column1;
public String getColumn0() {
return column0;
}
public void setColumn0(String column0) {
this.column0 = column0;
}
public String getColumn1() {
return column1;
}
public void setColumn1(String column1) {
this.column1 = column1;
}
}
private class TableModel extends AbstractTableModel {
private List<ModelObject> data;
protected TableModel(List<ModelObject> data) {
super();
this.data = data;
}
@Override
public int getRowCount() {
return data.size();
}
@Override
public String getColumnName(int column) {
switch (column) {
case 0:
return "Header 0";
case 1:
return "Header 1";
}
System.err.println("Only two columns are known in this table model");
return "???";
}
@Override
public int getColumnCount() {
return 2;
}
@Override
public Object getValueAt(int rowIndex, int columnIndex) {
ModelObject o = data.get(rowIndex);
switch (columnIndex) {
case 0:
return o.getColumn0();
case 1:
return o.getColumn1();
}
System.err.println("Only two columns are known in this table model");
return null;
}
}
public static void main(String[] args) {
SwingUtilities.invokeLater(new Runnable() {
@Override
public void run() {
new TestTable().initUI();
}
});
}
protected void initUI() {
Random r = new Random();
Vector<ModelObject> data = new Vector<TestTable.ModelObject>();
for (int i = 0; i < 10; i++) {
ModelObject o = new ModelObject();
o.setColumn0("Some stuff in column 0 " + i);
o.setColumn1("Some other stuff in column 1 " + r.nextInt());
data.add(o);
}
table = new JTable(new TableModel(data));
f = new JFrame();
f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
f.setSize(300, 300);
f.setLocationRelativeTo(null);
f.add(new JScrollPane(table));
f.setVisible(true);
}
}
在这里，所有内容都在一个类中编写，但是您当然应该将它们分开以正确遵循MVC模式。
