TableViewSections are shwon as Rows

Hey,

i createt a TableView and added two Sections with 1 Row each:

var sectionTitle = Ti.UI.createTableViewSection({ headerTitle: 'Title' });
sectionTitle.add(Ti.UI.createTableViewRow({title: "title"}));
 
var sectionAmount = Ti.UI.createTableViewSection({ headerTitle: 'Amount' });
sectionAmount.add(Ti.UI.createTableViewRow({title: "amount"}));
 
var billTable = Titanium.UI.createTableView ({
    sections: [sectionTitle, sectionAmount],
    top: 150
});

Title
title
Amount
amount

Title   Amount
title   amount

var billTable = Titanium.UI.createTableView ({
    data: [sectionTitle, sectionAmount],
    top: 150
});

Any ideas?

Thanks!
