Table control is used to handle multiple input records.
example for creating customer we use screen xd01.
initial screen we have address details,most of the fields on
this screen are fixed. But when you select payment
transactions you find customer bank details.Now we can see
customer can have multiple bank accounts (bank keys,bank
account no)In the table control row no for each record is
dynamic i.e for 1st record the fields are knbk-banks(01),
knabk-bankl(01)..here 01 specifies the row no and row no
keeps on increasing with every new record.

In bdc we declare a internal table t_knb1 type knb1 customer
bank details.

declare index
data v_index(2) type N.
declare string
data v_enam like bdcdata_fnam
loop at it_banks into wa_banks.
v_index = sy-tabix."loop counter

concatenate 'knbk-banks(' v_index ')'into v_fnam.
wa_bdcdata-fnam = v_fnam.
wa_bdcdata-fval = wa_banks-banks.
append wa_bdcdata to it_bdcdata.

repeat this procedure for all fields.
