Is there any way to implement row span and colspan in JTable like html table.

The rowspan and colspan are the attributes of <td> tag. These are used to specify the number of rows or columns a cell should merge. The rowspan attribute is for merging rows and the colspan attribute is for merging columns of the table in HTML.
Of course, you can mix colspan and rowspan to get a range of various tables. Example 4-13 demonstrates a mix of column and row spanning.
You can use the getRowCount() method: Returns the number of rows that can be shown in the JTable , given unlimited space. If a RowSorter with a filter has been specified, the number of rows returned may differ from that of the underlying TableModel .
The TableModel interface specifies the methods the JTable will use to interrogate a tabular data model. The JTable can be set up to display any data model which implements the TableModel interface with a couple of lines of code: TableModel myData = new MyTableModel(); JTable table = new JTable(myData);
Here is a really old example. I don't know if it still works:
