first of all something you should know: According to the Official Android Dev Pages, Views (and a TextView derives from View) do not support the setting of Margin, but ViewGroups (such as LinearLayout, RelativeLayout etc...) do.

So what you could do is the following:

TableLayout.LayoutParams params = new TableLayout.LayoutParams();
params.setMargins(5, 5, 5, 5);
TextView view = new TextView(this);
view.setLayoutParams(params);

This would set the margin for all children to 5 pixels - I tried it and it worked for me (albeit with a LinearLayout with vertical alignment). Give it a shot and let me know if I can help further :) .
