Initialisieren TableLayout in XML und programmgesteuert ausfüllen - Android (java)

Ich versuche zu initialisieren, ein TableLayout in XML und dann füllen Sie es in programmgesteuert. Hier ist mein XML -, java-und LogCat-Ausgabe.

Highscores.java

public class Highscores extends Activity {

    TableLayout table;
    TableRow rowHeader, row1, row2, row3, row4, row5, row6, row7, row8, row9, row10;
    TextView rank, percentage, score;
    Button btn1;    

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

        TableLayout table = (TableLayout)findViewById(R.id.tableLayout);

        TextView rank = (TextView)findViewById(R.id.rank);
        rank.setText("RANK");
        TextView percentage = (TextView)findViewById(R.id.percentage);
        percentage.setText("PERCENTAGE");
        TextView score = (TextView)findViewById(R.id.score);
        score.setText("SCORE");

        TableRow rowHeader = (TableRow)findViewById(R.id.rowHeader);

        rowHeader.addView(rank);  //Line 39
        rowHeader.addView(percentage);
        rowHeader.addView(score);

        Button btn1 = (Button)findViewById(R.id.homeBtn);

        table.addView(rowHeader, new TableLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));

        btn1.setOnClickListener(new OnClickListener() {
            public void onClick(View arg0) {
                Intent intent = new Intent(Highscores.this, MainMenu.class);
                startActivity(intent);
            }
        });
    }
}

highscoresmain.xml

<TableLayout 
    xmlns:android="http://schemas.android.com/apk/res/android"

    android:layout_weight="0"
    android:padding="5dp">

    <TableRow 
        android:layout_height="wrap_content"
        android:id="@+id/rowHeader">
        <TextView
            android:id="@+id/rank"
            android:layout_height="wrap_content" />
        <TextView
            android:id="@+id/percentage"
            android:layout_height="wrap_content" />
        <TextView
            android:id="@+id/score"
            android:layout_height="wrap_content" />
    </TableRow>
      </TableLayout>

Was ich will ist ein einfaches 3-Spalten-Tabelle mit Zeile 1 überschriften als "RANG", "PROZENTSATZ" UND "SCORE". Später werde ich weitere 10 Zeilen, die ich ziehen aus einer SQLite-Datenbank, aber ich werde das angehen danach.
