Android :: Adding Table Row By Inflating Does Not Take Table's Settings

I have a table layout with a few predefined rows in it. Each row has only two columns.

Now I need to dynamically add additional rows in it.

I have two problems:

1) When programmatically inflating, I cannot set the index of the newly created row (I want it in place 'n') 2) After inflation, the inserted (actually appended) row doesn't listen to parent table's stretch column property.

So here are my questions:

q1) Can I set the place where to insert the inflated row programatically ?

q2) Why doesn't the new row inflate properly (the second column is not shown because the first column doesn't contains a TextView with fill_parent.

In the end I need the first column to occupy 80% of the screen width, and the second column remaining 20%.

q3) is that doable with programmatic row insertions ?
