          final TableRow tr_head2 = new TableRow(GridDynamic.this);
          tr_head2.setId(10);
          tr_head2.setBackgroundDrawable(getResources().getDrawable(R.drawable.fab_label_background));
          tr_head2.setPadding(10, 10, 10, 10);
          tr_head2.setLayoutParams(new TableLayout.LayoutParams(
                        TableLayout.LayoutParams.FILL_PARENT,

       ScrollView scroll = new ScrollView(GridDynamic.this);
       scroll.setLayoutParams(new TableRow.LayoutParams(TableRow.LayoutParams.FILL_PARENT,

       scroll.addView(tr_head2);

Answer 1

EDIT : note that this answer was for original question asked here (re. deleting table row)....question has since been edited.

When you're adding row to table set tag associated with it

        tableRow.setTag(<some key associated with this row>);
        tableLayout.addView(tableRow);

Then you can do following to delete the row.

        View view = tableLayout.findViewWithTag(key);
        if (view != null) {
            tableLayout.removeView(view);
        }
