1. create a table row layout with button and inflate it.
2. you can create button dynamically and add it in your table row see below code for creating buttons dynamically .

 TableRow.LayoutParams params = new TableRow.LayoutParams(TableRow.LayoutParams.WRAP_CONTENT,TableRow.LayoutParams.WRAP_CONTENT);
    Button button = new Button(this);
    params.weight = 1;
    params.gravity = Gravity.CENTER;
    tablerow.addView(button,params);
here this is context of activity
