You should be able to find one in the current patrol ops pam, but they're really pretty simple. All you need is a matrix that gives the key information such as sub-unit assigned to conduct patrol, timings, purpose/recce questions, routes/objective, special sp arrangements, callsigns, etc. A patrol task table is not intended to replace patrol orders-it is a planning and coord tool- so it does not need to be overly complex.
