Invert functionality of row and column in JTable

I want to display data about a Java Object in a JTable in my GUI. In a traditional JTable the rows are Objects (or whatever data representation) and the columns describe the data of the objects. I want to do the opposite. I want the rows to list the name of the data of the object and the column to show the value of the data. I will only have 1 object in the table so I want the table to display data vertically instead of horizontally if that makes sense.
It appears that JTable is not designed to flip the functionality of rows and columns so my question is what is the best way to implement this? I know all of the names of the data I want to include as rows so I think I could just hardcode everything, but that doesn't seem very elegant.

When to use convertRowIndexToModel

I have some JDialogs displaying JTables.
When the header columns are clicked a sort occurs on that column.
My question is : how can I know when a column header has been clicked and thus made a sort active.
When the sort is active, I know I should user the .convertRowIndexToModel method.
But how do I detect that a column is sorting in order not to mess the correct index if no sort is active?

Generally speaking, you should ALWAYS uses the convertRowIndexToModel when you take an index value from the view (JTable) and try and look up some value within the model. The JTable does this automatically when you use it's methods, but incase you're not, you need to take care of it yourself.
There's no need to know if the view is sorted or not...
If you "really" want to know when a table is sorted, you could attach a RowSorterListener to the TableRowSorter used by the table.
You could also use the TableRowSorter#getSortKeys to see which columns are included in the sort...

I have used it for my selection table. When the auto order is activated (setAutoCreateRowSorter(true))
the indices of the model table and the visual change, so you have to tell it to look for it within the model with respect to the one you are seeing.
((CustomTable)form.getAvailListView().getModel()).data.get(form.getListView().convertRowIndexToModel(i))

How can I hide a row in my JTable?

I'm using Eclipse Indigo SR1 with JDK 1.7, on Windows 7 Pro.
I've written a desktop app, Swing based.
My app includes a JTable; it shows many records of type T, one row per record.
The table model points to Vector vect, named vect, containing all data to be shown in the JTable.
The app includes a combo, named sele, showing three values: 0, 1, 2.
When sele = 0, every record of vect has to be visible in the JTable.
When sele = 1, the JTable has to show only vect records having odd row index and all records with even row index mustn't be visible. Viceversa, when sele = 2.
So, here's my question: how can I make a row not visible in the JTable ?
I can't use the table model, because it points to vect that contains "all" data.
I tried a table cell renderer, but it seems that you can set the color of a cell, but you can't set it not visible or modify its size.
I've tried another way: if r is the row index, and I want that row to be not visible, I write table.setRowHeight(r,0), but this instruction throws an exception, the height can't be set to zero.
I could solve the problem by splitting the data, dividing vect in two, but I don't like that.
Does anybody have an idea ?
thanx in advance,
William
PS: someone told me to create a filtering TableModel that wraps the existing TableModel. The filtering model would be sensitive to the filtering criteria and fire the appropriate methods (TableDataChanged) when the filter was changed. The getRowCount method would return the filtered count. The getValueAt method would map the filtered row to the actual row in the underlying TableModel.
Mah, perhaps it's a good idea, but frankly I'm not able to understand it...

Use a TableRowSorter - which is:
An implementation of RowSorter that provides sorting and filtering using a TableModel. ..

How to insert a column at a specific position in JTable

I have a JTable with a predefined model
how to ask the model to insert a specific column in a specific position ?
so i want something like : DefaultTableModel.insertRow(int,Object[]) for columns

There is no insertColumn method like DefaultTableModel.insertRow() for inserting rows. In order to insert a column at a particular position, you must append the column using DefaultTable.addColumn() and then move the new column into the desired position.
JTable table = new JTable(rows, cols);
table.setAutoCreateColumnsFromModel(false);
DefaultTableModel model = (DefaultTableModel)table.getModel();
TableColumn col = new TableColumn(model.getColumnCount());
col.setHeaderValue(headerLabel);
table.addColumn(col);
model.addColumn(headerLabel.toString(), values);
table.moveColumn(table.getColumnCount()-1, vColIndex);

Is it really necessary to add the column in your TableModel at a specific index ? You can more easily adjust the column order in the view (the JTable) as documented in the class javadoc of JTable
By default, columns may be rearranged in the JTable so that the view's columns appear in a different order to the columns in the model. This does not affect the implementation of the model at all: when the columns are reordered, the JTable maintains the new order of the columns internally and converts its column indices before querying the model.
This is achieved by using the JTable#moveColumn method.
Adding a column to your DefaultTableModel is done calling the DefaultTableModel#addColumn method

With DefaultTableModel:
At the end one has to call fireDataChanged. There is only an addColumn with several overloads. This is no hindrance as the order of display is independent. One may move a column to another position, and has to take care of view index != column index. To get the correct view index immediately after adding the column, one has to access the JTable and call moveColumn.
I found it at times easier to create a new TableModel and assign that. Or not use the DefaultTableModel.

JTable RowFilter

Is is possible to some how get the index of the selection corresponding to the non filtered table?
After the table is filter using a regexFilter. JTable getSelectedRow returns the index of the filtered table?

If you are using the built in TableRowSorter functionality from 1.6 you can use the convertRowIndexToModel() on the table. This is give you the unfiltered index of the selected row.
The javadoc for JTable gives a description of this:
Coordinate conversions will be
necessary when using the row based
methods of JTable with the underlying
TableModel. All of JTables row based
methods are in terms of the RowSorter,
which is not necessarily the same as
that of the underlying TableModel. For
example, the selection is always in
terms of JTable so that when using
RowSorter you will need to convert
using convertRowIndexToView or
convertRowIndexToModel.

store the row id in your datamodel, when you get the selected row from jtable, query that rows ID.
