Edit 1:

For something like Html there the percentage width works with respect to its Parent

but the weight introduced in Android works with respect to the screen size available for root.

You can use a LinearLayout and the weight attribute to achive this.

<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:weightSum="1.0">

The child elements in your Rows can each be given a weight as a portion of the sum (a percentage). Be sure to set the layout_width to "0dp"

<Button 
android:layout_height="wrap_content"
android:layout_width="0dp"
android:layout_weight="0.5" />

<Button
android:layout_height="wrap_content"
android:layout_width="0dp"
android:layout_weight="0.5" />

The TableLayout has properties similar to LinearLayout. I did some tweek on it too. To better say it, see my sample code below. Hope its useful.

 <TableLayout
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:stretchColumns="3" >

        <TableRow
            android:id="@+id/tableRow1"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content" 
            android:orientation="horizontal"
            android:layout_weight="1">
            <TextView android:text="@string/test1" android:layout_weight="1"></TextView>
            <TextView android:text="@string/test2" android:layout_weight="1"></TextView>
            <TextView android:text="@string/test3" android:layout_weight="1"></TextView>
        </TableRow>

        <TableRow
            android:id="@+id/tableRow2"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content" 
            android:orientation="horizontal"
            android:layout_weight="1">
            <TextView android:text="@string/test1" android:layout_weight="1"></TextView>
            <TextView android:text="@string/test2" android:layout_weight="1"></TextView>
            <TextView android:text="@string/test3" android:layout_weight="1"></TextView>
        </TableRow>

        <TableRow
            android:id="@+id/tableRow3"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content" 
            android:orientation="horizontal"
            android:layout_weight="1">
            <TextView android:text="@string/test1" android:layout_weight="1"></TextView>
            <TextView android:text="@string/test2" android:layout_weight="1"></TextView>
            <TextView android:text="@string/test3" android:layout_weight="1"></TextView>
        </TableRow>

    </TableLayout>
