Abap2xlsx create worksheet how to set fields in header line without filtersymbol?

Question

Hello Forum,
I am using a package of abap2xlsx (Excel Export ABAP 2 XLSX)   and some methods from zcl_excel classes to create a worksheet for internal table gt_table and download it.
Following is some Koding I am using,
When the excel worksheet is downloaded, the header line contains filter symbols in all header fields, when using method bind_table (see A:).
Is there a way to set the header line fields without a filtersymbol?
if I replace the call on method bind_table (see A:)  by call on method convert (see B:)
then there are no filtesymbols, but in this method I cannot give a fieldcatalog table as exporting parameter.
And I want to change the texts in the header.
Thanks for any suggestions,
Regards Henricus Kroft

Dear SeánMacGC thanks for reply,
But "a.changed" is not a field in GNMT_CUSTOMER_MASTER_CHG. what i am doing in this procedure is i am collecting bulck data and validating field by field from GNMT_CUSTOMER_MASTER_CHG with GNMT_CUSTOMER_MASTER table as their structure is same.. if v_name is not same as v_name_chg then i am setting changed flag to "Y" changed is "changed dbms_sql.varchar2_table" and updating GNMT_CUSTOMER_MASTER in bluck where changed flag ='Y'...
type custRec is record
n_cust_ref_no dbms_sql.number_table,
v_name dbms_sql.varchar2_table,
v_name_chg dbms_sql.varchar2_table,
rowid rowidArray,
*changed dbms_sql.varchar2_table*
i cannot use simple SQL as i need to validate field for each records with GNMT_CUSTOMER_MASTER_CHG and insert into log file as well.....
to run this procedure:
execute DO_DC_NAME_UPDATE_OTHER_TAB.DO_NAME_UPDATE_OTHER_TAB;
Thanks...
