So you add a delegate to a QTableWidget, and then add the extra behavior you want.

Though honestly I wouldn't call an MS Excel grid a native type - it does require using the MS Excel Active X control at the very least, which you get as part of VisualStudios, but is not necessarily on the Windows platform unless someone else has put it there - either through installing Office or another App that pulled the ActiveX control along. Either way, you should be able to use that ActiveX control through the MFC/ActiveX windows Qt extension (ActiveQt), but (I believe) that requires limiting yourself to Windows.

float myValue = 3.1458;
QString myQStringValue = QString("%1").arg(myValue,0,'f',4');
QLabel* someLabel = new QLabel(myQStringValue); // or use setText() to update

Or alternatively:

char buffer[1024];
float myValue = 3.1458;
snprintf(buffer,sizeof(char)*1024,"%0.4f",myValue);
QString myQStringValue = QString(buffer);
QLabel* someLabel = new QLabel(myQStringValue);

Don't know how that isn't so simple...
