TableLayout is a ViewGroup that displays child View elements in rows and columns.

Start a new project named HelloTableLayout.

Open the Resources/Layout/content_main.xml file and insert the following:

<?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="fill_parent"
    android:stretchColumns="1">

    <TableRow
        android:layout_width="match_parent"
        android:layout_height="match_parent">
        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_column="1"
            android:text="Open..."
            android:padding="3dip"/>
        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="Ctrl-O"
            android:gravity="right"

            android:text="Quit"
            android:padding="3dip"/>
    </TableRow>
</TableLayout>

Notice how this resembles the structure of an HTML table. The TableLayout element is like the HTML <table> element; TableRow is like a <tr> element; but for the cells, you can use any kind of View element. In this example, a TextView is used for each cell. In between some of the rows, there is also a basic View, which is used to draw a horizontal line.

Make sure your HelloTableLayout Activity loads this layout in the OnCreate() method:

protected override void OnCreate (Bundle savedInstanceState)
{
    base.OnCreate (savedInstanceState);
    SetContentView (Resource.Layout.Main);
}

The SetContentView(int)) method loads the layout file for the Activity, specified by the resource ID — Resource.Layout.Main refers to the Resources/Layout/Main.axml layout file.

Run the application. You should see the following:
