Why my TableLayout isn't allowed to be inflated?

For a widget I use a simple layout which contains a TableLayout

<?xml version="1.0" encoding="utf-8"?>
<TableLayout  xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent"
    android:layout_height="wrap_content">
    <TableRow >
         (...)
    </TableRow>
</TableLayout>

But when a I want to update its content by creating a RemoteViews

RemoteViews eventElementLayout = new RemoteViews( this.getPackageName(), R.layout.widget_events_element );

I got an exception telling me that TableLayout is not allowed to be inflated.

App widgets only allow limited list of layout and view widget types that can be used within them. It looks like TableLayout isn't supported. From Google developers documentation:

A RemoteViews object (and, consequently, an App Widget) can support the following layout classes:

* FrameLayout
* LinearLayout
* RelativeLayout

And the following widget classes:

* AnalogClock
* Button
* Chronometer
* ImageButton
* ImageView
* ProgressBar
* TextView

Descendants of these classes are not supported.
