Given that you already have a field-symbol pointing at your original type named: <orgTable> and it also assumes that your table's row type is a structure, it wouldn't be too hard to modify it to support other types of line types. The following should work (although haven't tried it in the ABAP ide):

data lineType type ref to cl_abap_structdescr.

data tableType type ref to cl_abap_tabledescr.

data componentTable type component_table..

tableType ?= cl_abap_tabledescr=>describe_by_data( <orgType> ).

lineType ?= tableType->get_table_line_type( ).

componentTable = lineType->get_components( ).

append your additional type here.
append fooType to componentTable.

lineType ?= cl_abap_structDescr=>create( componentTable ).

tableType = cl_abap_tabledescr=>create( lineType ).

now create your new data area.

data newTable type ref to data.

field-symbol <newTable> type standard table.

create data newTable handle tableType.

assign newTable->* to <newTable>.

Hope this is helpful, Do reward.

Hi,

when u create a internal table structure, instead of append use insert statement and specify the position of that particular field. then u can use it as a first field r whatever.
