I am not sure to have understood what you mean by "a 'source' table in
Table form," since after evaluation myTableS is a list with head *List*.
So the "Table form", whatever that means, stay in this form only as
long as the expression has not been evaluated (or some *Hold...*
attribute is used).

What you format is a /list/. You can format it as a table, a matrix, or
a grid for instance.

I may not have understood at all what you want, but the untable thing
could be achieve with a *Case* function, as in the following example.
myTableS = {{a, b}, {c, d}, {e, f}}
myTableF = TableForm[myTableS, TableHeadings ->
{{"r1", "r2", "r3"}, None}]
First[Cases[myTableF, myTableS]]
