Using net.sf.jasperreports.export.xls.pattern

[surkoff-v]

How can I use net.sf.jasperreports.export.xls.pattern ?
I try
SimpleXlsReportConfiguration configuration = new SimpleXlsReportConfiguration(); configuration.setDetectCellType(true); // false also don't help
ColumnBuilder clmb = ColumnBuilder.getNew(); clmb.addFieldProperty("net.sf.jasperreports.export.xls.pattern","[h]:mm");
but is has no effect on excel. I got "General" format cells Category or "Text" depends on detectCellType

my field type isn't Date it is special formatted string. My DJ version 5.3.0
