You are creating TableLayout inside LinearLayout which is not correct. Make ScrollView as root layout.

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">

<LinearLayout
android:id="@+id/linearLayout1"
android:layout_width="fill_parent"
android:layout_height="wrap_content" 
android:gravity="center">

<AutoCompleteTextView
android:id="@+id/autoCompleteTextView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:ems="10"
android:text="AutoCompleteTextView" >

<requestFocus />

</AutoCompleteTextView>

</LinearLayout>

<ScrollView 
android:id="@+id/scrollview1"
android:layout_width="fill_parent" 
android:layout_height="fill_parent"
android:orientation="vertical" android:layout_marginTop="10dip">

<TableLayout  android:layout_height="wrap_content"
          android:layout_width="wrap_content"
          android:id="@+id/itable">
<TableRow
         android:id="@+id/trstate"
         android:layout_height="wrap_content"
          android:layout_width="wrap_content">

 </TableRow>
 <TableRow
         android:id="@+id/trimage"
         android:layout_height="wrap_content"
          android:layout_width="wrap_content"
        >
<ImageView  
         android:id="@+id/iimage"
 android:layout_width="wrap_content"
    android:layout_height="wrap_content"
                 />

<TextView
    android:id="@+id/tstate"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="NewYork"
    android:textAppearance="?android:attr/textAppearanceLarge" />

</TableRow>

</TableLayout>

</ScrollView>

</LinearLayout>

Edit:

 public class SampleAndroidActivity extends Activity {
/** Called when the activity is first created. */

public TableLayout itable;
public TableRow trimage;
public TableRow trstate;
public ImageView iimage;
public TextView tstate;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    itable = (TableLayout) findViewById(R.id.itable);
    /*Remove this line 
     * itable.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT,
     * LayoutParams.WRAP_CONTENT));
     */

    for (int i = 0; i < 3; i++) {

        trstate = new TableRow(this);
        trstate.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT,
                LayoutParams.WRAP_CONTENT));

        tstate = new TextView(this);
        tstate.setLayoutParams(new LayoutParams(50, 50));
        tstate.setText("NewYork");
        trstate.addView(tstate);

        trimage = new TableRow(this);
        trimage.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT,
                LayoutParams.WRAP_CONTENT));
        for (int j = 0; j < 3; j++) {
            Log.i("Test", Integer.toString(i) + "-" + Integer.toString(j));
            iimage = new ImageView(this);
            iimage.setPadding(8, 8, 8, 8);
            iimage.setLayoutParams(new LayoutParams(100, 100));
            iimage.setImageResource(R.drawable.events);
            trimage.addView(iimage);
        }
        itable.addView(trimage);
        itable.addView(trstate);

    }

}
}
