I don't think table header is editable and so you can't set a cell editor for that. You may try below,<br />
<br />
1. When you want to edit the text field on the table header, just show a editable text field just on top of the header field( use windo as container? ).<br />
2. When the user type text and press enter, get the text from the editable TF and hide it and then set the text to the header text fields.

I want to change my JTable and add above each column header label a TextField / Combo that will be used for filtering.<br />
<br />
I started doing so by implementing a TableCellRenderer and in the <br />
getTableCellRendererCompon<wbr />ent I am returning a panel with two rows, one for the Input and one for the Label.<br />
<br />
It looks good but I could not focus on that input (not with the mouse and not with the keyboard) it's like the input is disabled.<br />
I thought of adding a MouseListener to the input and activate event my selt but they did not work.<br />
<br />
How can I do this?

&quot;Disabled&quot; input when used as a table's header component

Java is a platform-independent, object-oriented programming language and run-time environment, designed to have as few implementation dependencies as possible such that developers can write one set of code across all platforms using libraries. Most devices will not run Java natively, and require a run-time component to be installed in order to execute a Java program.
