How can I remove a column from a JTable with dragging?

focus issue using a JComboBox as a cell editor in a JTable
I'm having issues with the following code, where I use a JComboBox to change a String value in a table cell. The JComboBox works fine, but if I click in the box and then click away without selecting anything the JComboBox's dropdown remains visible, even if I delete the row. Clicking on another Swing component like a JButton often caus...
JTable with a complex editor
I have many custom editors for a JTable and it's an understatement to say that the usability, particularly in regard to editing with the keyboard, is lacking. The main reason for this is that my editors are always created with a similar (though often more complex) situation to this: @Override public Component getTableCellEditorComponen...

Swing GUI : Scrolling not updated when a JTable gets bigger
Hi, I got a Java Swing GUI and got a problem with a JTable in a JScrollPane. For some reason, when the rows of the table model are increased during the program execution, the JScrollPane isn't updated - that is, if the rows are increased so that the height of the table is over the height of the scroll view, the scroll panes aren't updat...
An efficient way to display a time counter in a JTable cell
A time counter shows the age in seconds of a row in the table. Ideally, it would be updated once per second. I know I can just increment the appropriate data in the table model, fire the events (one per row), etc. It seems like overkill. Is there a better, lighter way? ...

Change the Ctrl + click behaviour on a JTable
Is there an easy way to manipulate the controls on a JTable to give different functionality when there is a keyboard button pressed (ie. CTRL button) and a row is selected? I've been asked to create a table where the CTRL + Click (mouse click) on a row will only deselect a selected row, never select a row. If the user CTRL + Clicks an un...
Strategy for detecting an object in JTable row?
Here's the thing: a sortable JTable backed by JTableModel with an array of objects that populate rows (one object = one row). Need to delete rows. Without sorting, deleting an object is simple: get selected row index, delete array object under the same index. With sorting, though, row indexes mess up in a sense that they no longer match...

If the columns of my JTable are unalphabetized, I can use getSelectedRows() and get values of their rows without any trouble. But, if the user clicks on the column name and the rows are alphabetized in that column, getSelectedRows() returns not the currently selected rows, but the rows that were originally there before alphabetization. ...

keeping JTable selection in viewport
I'm using GlazedLists to autogenerate an EventTableModel from an EventList, for use with a JTable in a JScrollbarPane. I'm using the EventList as a FIFO, a bunch of elements are added to the end, then a bunch of elements are sometimes removed from the beginning. When elements are removed, the selection works exactly as I expect: even th...
