Have you tried specifying a formatting function instead of the "inline" method you've shown above?
....},
{
name: 'pocphone',
alias: 'Phone #',
format: {
template: "formatPhone"
}
},....
function formatPhone(value) {
.
.
.
}
I thought I've done this using a featureTable ( I have with plain old dGrid) but I can't track down my own code..
