在表佈局中橫跨2行進行拉伸

Question

如何在TableLayout中跨2列進行拉伸。我有2行帶有標籤，並在1行上編輯文本，我希望在整個第二行有一個按鈕。這裏

<?xml version="1.0" encoding="utf-8"?> 
<TableLayout 
    xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_height="fill_parent" 
    android:layout_width="fill_parent" 
    android:background="#000000" 
    android:stretchColumns="1"> 

    <TableRow> 
     <TextView 
      android:text = "Name: " /> 
     <EditText 
      android:id = "@+id/txtAddName" 
      android:gravity = "right" 
      android:layout_width = "fill_parent" /> 
    </TableRow> 
    <TableRow> 
     <TextView 
      android:text = "Phone: " /> 
     <EditText 
      android:id = "@+id/txtAddPhone" 
      android:gravity = "right" 
      android:layout_width = "fill_parent" />   
    </TableRow> 
    <TableRow> 
     <Button 
      android:id = "@+id/btnAdd" 
      android:text = "Add Entrie" 
      android:layout_width = "fill_parent" /> 
    </TableRow> 
    <TableRow> 
     <Button 
      android:id = "@+id/btnShow" 
      android:text = "Show all Entries" 
      android:layout_width = "fill_parent" /> 
    </TableRow> 
    <TableRow> 
     <Button 
      android:id = "@+id/btnDelete" 
      android:text = "Delete all Entries" 
      android:layout_width = "fill_parent" /> 
    </TableRow> 
</TableLayout>
