JTable 单元格中的 JButtons 在行选择时改变形状
JButtons in JTable cell change shape on row selection
我每行有一个单元格（列）table，单元格是一个面板，上面有 2 个按钮。 TableCellRenderer 和 TableCellEditor 已正确实现以允许呈现和编辑单元格。但是当我点击行甚至按钮时，按钮的形状会改变。看起来按钮的大小缩小以适合按钮文本。请参阅所附图片。
如果我设置了按钮的首选大小，那么大小似乎没有改变，但按钮文本向右移动。下面是 table 单元面板的代码。 运行从如下所示的相同 class 中的主面板打开此面板不会显示此行为。此行为仅在将此面板用作单列 table 行中的单元格时可见。不知道哪个 属性 哪个 set/change.

添加示例代码以帮助重现问题。 运行 主要在NewJFrame1 class 看问题。取消注释并 运行 TableRowPanel1 private class 中的 main 以查看默认的正确工作。如果我直接在 JFrame 中使用 table 单元格面板组件，它工作正常。但是通过编辑器用作 table 单元格的相同组件显示了问题。请真的需要帮助。:

根据源代码，根据FlatBorder规范，table单元格编辑器的边框插入为0。
com/formdev/flatlaf/ui/FlatBorder.java
protected boolean isCellEditor( Component c ) {
return FlatUIUtils.isCellEditor( c );
}
@Override
public Insets getBorderInsets( Component c, Insets insets ) {

// ...
com/formdev/flatlaf/ui/FlatUIUtils.java
public static boolean isCellEditor( Component c ) {
// check whether used in cell editor (check 3 levels up)
Any ideas about how to rectify this?
将单元格编辑器面板层次结构设为三级或更多级。

或覆盖 FlatBorder#isCellEditor(Component c) 方法以始终 return false.

添加示例代码以帮助重现问题。 运行 主要在NewJFrame1 class 看问题。取消注释并 运行 TableRowPanel1 private class 中的 main 以查看默认的正确工作。如果我直接在 JFrame 中使用 table 单元格面板组件，它工作正常。但是通过编辑器用作 table 单元格的相同组件显示了问题。请真的需要帮助。:

根据源代码，根据FlatBorder规范，table单元格编辑器的边框插入为0。
com/formdev/flatlaf/ui/FlatBorder.java
protected boolean isCellEditor( Component c ) {
return FlatUIUtils.isCellEditor( c );
}
@Override
public Insets getBorderInsets( Component c, Insets insets ) {
// ...
if( isCellEditor( c ) ) {
// remove top and bottom insets if used as cell editor
insets.top = insets.bottom = 0;
// ...
com/formdev/flatlaf/ui/FlatUIUtils.java
public static boolean isCellEditor( Component c ) {
// check whether used in cell editor (check 3 levels up)
Any ideas about how to rectify this?
将单元格编辑器面板层次结构设为三级或更多级。
class TableRowPanel1 extends JPanel {
protected final JButton jButton1 = new JButton("jButton1");
protected final JButton jButton2 = new JButton("jButton2");
public TableRowPanel1() {

p2.add(jButton1);
p2.add(jButton2);
JPanel p1 = new JPanel(new BorderLayout());
p1.add(p2);
add(p1);
}
}
或覆盖 FlatBorder#isCellEditor(Component c) 方法以始终 return false.

public TableRowPanel1() {
