首先聲明
主要就是三個應用類ColumnGroup
import java

} else {
this
}
this

}
/**

* TableColumn or ColumnGroup
*/
public void add(Object obj) {
if (obj == null) {
return;
}
v
}
/**
* @param c
* TableColumn
* @param v
* ColumnGroups
*/
public Vector getColumnGroups(TableColumn c
g
if (ntains(c))
return g;

}

}

}
/**

*/
public java
return text;
}
/**

*/

2、GroupableHeader繼承自JTableHeader,為多表頭結構的管理者
import java.util.Enumeration;
import java.util.Vector;
import javax.swing.table.JTableHeader;
import javax.swing.table.TableColumn;
import javax.swing.table.TableColumnModel;
/**
* GroupableTableHeader
* @author flyx
*/
public class GroupableTableHeader extends JTableHeader {
private static final String uiClassID = "GroupableTableHeaderUI";
protected Vector columnGroups = null;
public GroupableTableHeader(TableColumnModel model) {
super(model);
setUI(new GroupableTableHeaderUI());
setReorderingAllowed(false);
setRequestFocusEnabled(false);
}
public void addColumnGroup(ColumnGroup g) {
if (columnGroups == null) {
columnGroups = new Vector();
}
columnGroups.addElement(g);
}
/**
*
* 創建日期:(2001-8-31 15:54:29)
*/
public void clearColumnGroups() {
columnGroups = null;
}
public ColumnGroup[] getColumnGroups() {
ColumnGroup[] retg=null;
if (columnGroups.size()>0) {
retg=new ColumnGroup[columnGroups.size()];
pyInto(retg);
}
return retg;
}
public Enumeration getColumnGroups(TableColumn col) {
if (columnGroups == null)
return null;
Enumeration enum = columnGroups.elements();
while (enum.hasMoreElements()) {
ColumnGroup cGroup = (ColumnGroup) enum.nextElement();
Vector v_ret = (Vector) cGroup.getColumnGroups(col, new Vector());
if (v_ret != null) {
return v_ret.elements();
}
}
return null;
}
/**
