Formating input text field

Is it possible to format an input field to accept phone or zipcode formats, ie: ###-###-#### or #####-####.

Thanks

It is possible to monitor changes and modify cell contents with onCellTextChanging() event. Here is an example which only allows numeric characters -

obj.onCellTextChanging = function(text, column, row){

if (column == 1) { // column-1 only
if (text.match(/[^0-9.+-]/)){
return "error"; // prevent non-digits
}
}
}
Something similar could work for phone/zipcodes(?)
