Pintar celdas de JTable al hacer clic

[Zoik]

Primeramente buenas a todos.

Bueno estoy empezando a mirar temas de heurísitica y he empezado haciendo la búsqueda del recorrido mas corto con el algoritmo A*.

Hasta aquí todo bien, pero me surge un problema y es que para testear todo esto, quiero hacer una JTable que al yo clicar en una celda de color blanco esta se pinte de color negro para dar a entender a la aplicación que es una celda infranqueable por el contrario si clico en una negra, se volverá blanca.

Básicamente el problema es que cuando selecciono la celda blanca, me vuelve negras esa y todas las siguientes.

A ver si me pudieseis echar una mano.
