What is the equivalent of "colspan" in an Android TableLayout?

It seems that there is an attribute doing that : layout_span

UPDATE: This attribute must be applied to the children of the TableRow. NOT to the TableRow itself.

Just to complete the answer, the layout_span attribute must be added to the child, not to TableRow.

This snippet shows the third row of my tableLayout, which spans for 2 columns.

<TableLayout>
    <TableRow
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" >

        <Button
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_span="2"
            android:text="@string/create" />
    </TableRow>
</TableLayout>

And this is how you do it programmatically

//theChild in this case is the child of TableRow
TableRow.LayoutParams params = (TableRow.LayoutParams) theChild.getLayoutParams();
params.span = 2; //amount of columns you will span
theChild.setLayoutParams(params);
