Answer 1

fieldcatalog in the sense, we can modify the alv table column names by using below code.
DATA LO_CMP_USAGE TYPE REF TO IF_WD_COMPONENT_USAGE.
LO_CMP_USAGE = WD_THIS->WD_CPUSE_ALV2( ).
IF LO_CMP_USAGE->HAS_ACTIVE_COMPONENT( ) IS INITIAL.
  LO_CMP_USAGE->CREATE_COMPONENT( ).
ENDIF.
DATA LO_INTERFACECONTROLLER TYPE REF TO IWCI_SALV_WD_TABLE .
LO_INTERFACECONTROLLER =   WD_THIS->WD_CPIFC_ALV2( ).
  DATA LO_VALUE TYPE REF TO CL_SALV_WD_CONFIG_TABLE.
  LO_VALUE = LO_INTERFACECONTROLLER->GET_MODEL(
  LO_VALUE->IF_SALV_WD_TABLE_SETTINGS~SET_VISIBLE_ROW_COUNT( 5 ).
for title
DATA: LR_TABLE_SETTINGS TYPE REF TO IF_SALV_WD_TABLE_SETTINGS.
DATA: LR_HEADER TYPE REF TO CL_SALV_WD_HEADER.
LR_TABLE_SETTINGS ?= LO_VALUE.
LR_HEADER = LR_TABLE_SETTINGS->GET_HEADER( ).
LR_HEADER->SET_TEXT( 'Waiting for Travel Advance Approval ' ).
**lr_table_Settings->set_Read_only( abap_false ).
DATA L_HEADER TYPE REF TO CL_SALV_WD_COLUMN_HEADER.
DATA: LO_COLUMN1 TYPE REF TO CL_SALV_WD_COLUMN.
LO_COLUMN1 = LO_VALUE->IF_SALV_WD_COLUMN_SETTINGS~GET_COLUMN( 'TRAVELID' ).
L_HEADER = LO_COLUMN1->GET_HEADER( ).
L_HEADER->SET_TEXT( 'Travel Adv ID' ).
DATA: LO_COLUMN2 TYPE REF TO CL_SALV_WD_COLUMN.
LO_COLUMN2 = LO_VALUE->IF_SALV_WD_COLUMN_SETTINGS~GET_COLUMN( 'PERNR' ).
L_HEADER = LO_COLUMN2->GET_HEADER( ).
L_HEADER->SET_TEXT( 'Employee Name' ).
In get_column you have to pass the attribute name
is this what you are looking?
