Creating Groups in JTable

Question

I am trying to create groups in a JTable based on item-type. For example, Item 1, 2, and 3 would be one type, while 4 and 5 would be another. I would also like to separate group 1 from group 2 with an empty row for visibility's sake.

Item Name	Time Created	Location	Color
Item 1	Item 1 time	Item 1 loc	Item 1 color
Item 2	Item 2 time	Item 2 loc	Item 2 color
Item 3	Item 3 time	Item 3 loc	Item 3 color
Item 4	Item 4 time	Item 4 loc	Item 4 color
Item 5	Item 5 time	Item 5 loc	Item 5 color

Is this possible with JTable or should I look into something else?
