cells cannot be merged in JTable

Here is how to make it look like cells are merged:
Suppose cells [r,c] and [r,c+1] are to be merged.
Install a cell renderer for the table.
To render either of the two merged cells,
render the contents to an offscreen buffer.
Then copy the lefthalf of the buffer for [r,c]
and the right half for [r+1,c].

You would have to setIntercellSpacing(new Dimension(0,0))
so there is no border between the two cells.
Obviously this will impact the appearance of the entire table.

The ugliness of this kluge suggests that you rethink the need to merge cells.
Maybe you want a GridBagLayout.

If you read his post carefully, I think he is telling your specifically not to do this. I have to say that your post is a bit short on important details that are necessary to give a good answer. So instead of asking for spoon-fed code, why not tell us exactly what you're trying to do here, and perhaps we can give you better alternatives?

A useful link I think: How to ask smart questions

Yes, I could give you the code for the kludge. But I'm a bit tied up at the moment.
Besides, if you can't do offscreen buffers (create, draw on, crop) and cell renderers,
it is not a good idea for you to venture into the inevitable morass.

Hi,

I want to separate the rows in a jtable and give a heading to the set of rows. so i want to merge cells in a jtable. is there any way that i can achieve this.

one way: Create a bunch of tables and place them next to each other on the screen.
