and custom msg.

Pass ui parameter to the callback function which may be anonymous or a named function.

function taxnumberIsValid( ui ){
     var country = ui.rowData["country"],
           value = ui.value; //value is taxno as entered in the editor
     //do the validation and if it fails assign message to ui.msg and return false
     if( validation fails ){
        ui.msg = "some message";     
        return false;
     }
}

{ title: "Country", dataIndx: "country" },
{ title: "tax number", dataIndx: "taxno",
  validations: [ { type: taxnumberIsValid }]
}
