How to merge two cells into one in JTable?

I need to do the table like this http://imgur.com/vrFmz . But I don't know how to merge two cells into one. What I need to do?

This screenshot doesn't tell exactly what you need.
Can you give me an example?

In this example, on first table you can see cell with string "Частота настройки, кГц" on the left side and three row on the right side. It's exactly what I need.

Sorry, I still don't get it.

I need to unite cells. This means that I make one big cell from two small cells. But I don't know how to do this on Java.

So you want the 3500 row at the bottom to be in the one above?

http://imgur.com/C7VmN Can you see the one cell on the left side and and two cells on the right side?

If you are wanting to do this with JTable then the simple answer is it doesn't support merging cells. You can however add such support or use a third party component that already has this feature added (such as JIDE grid, but it's not free). Not sure if there are any free implementations available but a quick search may get you what you want.
