is there any specific method or API to insert records into customized table.

is there any specific method or API to insert records into customized table.

Hello 
I have created one table using chrome extension by creating one separate section. That table is still empty. I just wanted to insert records in that table. I know that there is one insertRecords API ,but for this API we need to create XML format.and for creating XML that field name must be same as the output of getRecords. So i have added one empty table but unable to get field name of same table in response of getRecords..so is there any specific method or API to insert records into customized table.
Thanks
