after struggling with my code for two days, finally solved issue, my mistake was to use "ApplicationContext" instead of "Activity Context" ; i need to use TableRow row = (TableRow) Inflater.from(this).inflate(R.layout.attribute_row, table, false); instead of TableRow row = (TableRow) LayoutInflater.from(getApplicationContext()).inflate(R.layout.attribute_row, table, false);

After adding all rows you want just call this method on the table object to have the newly added rows reflect on the UI:

table.requestLayout();

I have a similar code and works fine by adding the requestLayout() method.

My dynamic table in layout xml file looks like this:

<TableLayout android:id="@+id/myTable"
    android:layout_width="match_parent" android:layout_height="match_parent"
    android:layout_marginLeft="15dp" android:layout_marginRight="15dp" android:layout_marginTop="5dp">

    <!--Dynamic content here-->

</TableLayout>

Note: android:layout_width for TableLayout and any other View containing it should be match_parent. Because wrap_content will cause resize issues when you add new rows.

Do not pass null as the parent when calling inflate(...) because it can't determine the attributes that are referencing the parent (e.g android:layout_width, android:layout_height).

Do instead:

TableRow row = (TableRow) LayoutInflater.from(getApplicationContext()).inflate(R.layout.attribute_row, table, false);

try to set table.addView(row,i);

or you can create and add row dynamically.

 TableRow row;

    for (int i = 0; i <=lstfDue.size(); i++)
    {
        row= new TableRow(this);
        row.setLayoutParams(rowParams);

        txtDate = new TextView(this);
        txtAmount = new TextView(this);

        txtDate.setText("text here");
        txtAmount.setText("text here");

        row.addView(txtDate);
        row.addView(txtFeeType);
        row.addView(txtAmount);
        tblFeesDue.addView(row, i);
    }
