title: How to set Excel cell format in iReport
body: <p>I'm trying to export a report as xls, but when i open my exported file i notice that all cell formats are Number and all data are wrote with ' like text data (integer fields and double fields also...) so i cant apply any formula like SUM in Excel.</p>
