In(@variable) clause and TABLE datatype variable

Hi this question has been asked several times and some solution has been
provided already. But the one I am facing is with a twist. I need to use the
IN() clause with a variable as its parameter. The variable is a list of comm
a
separated character values all enclosed in pairs of single quotes. I could
have solved this problem by enclosing the final query in a single quote and
running Exec command on it (with the Variable list outside the quotes) but I
also need to use a Table data type variable which raises error when EXEC
command is run.
Followig is the example that may explain well.
I have oversimplified this example and it does things that we would not do
in normal situation
use pubs;
-- declare and set Table variable
declare @.TableVariable TABLE ( col char(4) );
INSERT @.TableVariable
Select pub_id FROM publishers
;
--declare and set CSV single quoted characters list
declare @.ListVariable varchar(100);
set @.ListVariable = ' ''0736'', ''0877'' '; --these pub_ids are in the
publishers table, promise
--the query where the Table variable is used as well as the IN() clause is
used
Select TableVariable.col
From @.TableVariable as TableVariable
Where TableVariable.col IN (@.ListVariable)
-- returns 0 rows
--if we use Exec by replacing the last code section above with as following
declare @.command varchar(2000)
set @.command='
Select TableVariable.col
From @.TableVariable as TableVariable
Where TableVariable.col IN ('+@.ListVariable+')
'
exec (@.command)
--Then we get the error message:
-- Must declare the variable '@.TableVariable'.
