Java 比growx大的Grow表
我已将布局配置为：Java 比growx大的Grow表,java,swing,miglayout,Java,Swing,Miglayout,我已将布局配置为： panel.add(addButtons(), "wrap"); panel.add(showTable(), "growx, wrap"); 因此，首先我要添加一个按钮组，然后我想将我的表扩大到尽可能大，然后将下一个组件包装到下一个“行”中 但是，我的gui看起来是这样的： panel.add(addButtons(), "wrap"); panel.add(showTable(), "growx, wrap"); 在这
panel.add(addButtons(), "wrap");
panel.add(showTable(), "growx, wrap");
panel.add(addButtons(), "wrap");
panel.add(showTable(), "growx, wrap");
谢谢你的回答 您可以使用
javax.swing.table.TableColumn
TableColumn custom_column = yourTable.getColumnModel().getColumn(1); // 1 means column 1
custom_column.setPreferredWidth(500);
如果要加宽所有列，可以使用循环：
TableColumn custom_column ;
int numberOfColumns = yourTable.getColumnModel().getColumnCount();
for(int y= 0;y<numberOfColumns;y++){
custom_column=table.getColumnModel().getColumn(y);
custom_column.setMinWidth(500);
}
TableColumn自定义_列；
int numberOfColumns=yourTable.getColumnModel（）.getColumnCount（）；
对于（inty=0；y您可以使用javax.swing.table.TableColumn；
TableColumn custom_column = yourTable.getColumnModel().getColumn(1); // 1 means column 1
custom_column.setPreferredWidth(500);
如果要加宽所有列，可以使用循环：
TableColumn custom_column ;
int numberOfColumns = yourTable.getColumnModel().getColumnCount();
for(int y= 0;y<numberOfColumns;y++){
custom_column=table.getColumnModel().getColumn(y);
custom_column.setMinWidth(500);
}
TableColumn自定义_列；
int numberOfColumns=yourTable.getColumnModel（）.getColumnCount（）；
对于（int y=0；y
在这里，您显然无法从表中看到任何值。因此，如何增加表的大小，以便可以看到每个值
正如我在评论中所说，我认为您的问题不在于列（首选| min | max）的大小，而是布局管理器的默认行为：。如中所述，MigLayout
中的默认行不填充所有可用宽度，而只是显示最长行所需的宽度（基于组件宽度）。如果在实例化布局时启用“调试”功能，则可以看到这一事实：
MigLayout layout = new MigLayout("debug");
我理解你的问题，你需要结合growx
和fillx
约束。第一个是组件约束，另一个是布局约束
以上所说，PASASE考虑以下进展：
1.添加不带“growx”约束的滚动窗格

您是否尝试“填充”当用fill
替换growX
时，我得到：非法约束：“fill”
希望使用fillx
会有用。你可以将它与growX
结合使用，使行增长并被填充。@Vivien重写/设置JTabl的getPreferredScrollableSize的值e、 然后这个维度（由JScrollPane使用）将适当的PreferredSize返回到容器，并与TableColum.setPreferredWidth（500）一致；ForId您试图“填充”当用fill
