Thread: header into header and table into table

Hi, i have an idea for my program but i'm not able to realize it. Can someone help me?

I have a list of users, and a list of match related to users. I want to make table that shown all users and all matches, like in the picture. I thought to make a table-into-table try because first two columns are sortable and, for that reason, i think that to make a single table is not a good solution. Updating matches with a single table will become harder and surely not object oriented.

I want that the width of the green columns can be changed throught the title bar (red). My idea is

1) To make a class (JuserMatchData) with a static DefaultTableColumnModel (headers) and

2) call a JTable(TableModel dm, TableColumnModel JuserMatchData.headers) for every users. (Will this make the column width be syncronized?)

3) To place a JTable without data on the TableColumnModel of the main table (black) to build the red header. To hide all headers of the "data table".

[ 4) To add spoiler effect to hide matches ]

Is there a better way to obtain the same results? Can my idea works or the width will not be syncd?

CODE AND PROBLEMS WITH HEADERS
//**//**//**//**//**//**//**//**//**//**//**//**//**

I build the main table with userTable (that have only the first 2 columns filled) and userData.headers (described later).
JTable(userTable, userData.headers);

static userData.headers:

headers = new DefaultTableColumnModel();
 
col[0] = new TableColumn(0);
col[0].setHeaderValue("Id");
col[0].setMaxWidth(100);
col[0].setPreferredWidth(50);
col[0].setResizable(true);
 
col[1] = new TableColumn(1);
col[1].setHeaderValue("Nome");
col[1].setPreferredWidth(200);
col[1].setMaxWidth(200);
col[1].setResizable(false);
 
col[2] = new TableColumn(2);
col[2].setHeaderValue(new JTable(3,1)); //test with an empty table
col[2].setResizable(true);
 
headers.addColumn(col[0]);
headers.addColumn(col[1]);
headers.addColumn(col[2]);

The results :\

PS: i have the same results even i do
MYBLACKTABLE.setValueAt( new JTable(3,1), 0, 2);

thanks for help

more fails incoming.
Here a new class

public class JuserMatchData extends JTable implements TableCellRenderer {	
	public DefaultTableModel tableModel;	
	public static DefaultTableColumnModel columnModel;
	public static TableColumn[] col = new TableColumn [4];
 
	static {
 
		columnModel = new DefaultTableColumnModel();
		/* edit TableColumn and add to static columnModel */
	}
 
	JuserMatchData(){ //only head, for title
		super( new DefaultTableModel(  ), columnModel);
		tableModel = (DefaultTableModel) super.getModel();
	}
 
	JuserMatchData(user u){ //only body, for users
		super( new DefaultTableModel(  ), columnModel);
		tableModel = (DefaultTableModel) super.getModel();
//HOW can i remove title?
		tableModel.addRow(new Object[]{"IdL", "Sfid", "Gir", "Stat"});
	}
 
 
	@Override
    public Component getTableCellRendererComponent(JTable arg0, Object arg1,
    boolean arg2, boolean arg3, int arg4, int arg5) {
        return this;
    }
 
}

Now, in the code pasted in my first post i can replace the row

col[2].setHeaderValue(new JTable(3, 1));
// with
col[2].setHeaderValue(new JuserMatchData());

Here the result
java.JPG
(for testing purpose i placed a table even in the normal cell )

If i add

col[2].setCellRenderer(new JuserMatchData());
col[2].setHeaderValue(new JuserMatchData());

i have this result
java.JPG

If i undo and i add

JUsers.setDefaultRenderer(JuserMatchData.class, new JuserMatchData());  //JUsers is the table posted
//or 
JUsers.setDefaultRenderer(JTable.class, new JuserMatchData());

i have no changes, and i see the table like a string, like before.

Thanks for helps

PS:did u realized that i have to make 4 obj for my 4 column into an obj for the columnModel that, with an object for the tableModel, make my smaller table (class that implements TableCellRenderer and extend JTable) placed into the title of another TableColumn that is into a tableColumnModel that make another JTable (with its tableModel, ofc). Is theren't an easier way?
