How to remove System:index column in exported table

[Djordje Radonic]

Hello people.

I am using earth engine function to export results to google drive table via

Export.table.toDrive({
  collection: featureCollection,
  description: 'exportTableExample',
  fileFormat: 'CSV'
});

My featureCollection consists of features with several columns, among which there is no system:index column, but in my exported data table, there is (please check the link).

I assume system:index may be defined through export function, or when feature is made from dictionary.

If anyone knows how to remove system:index column using code inside the script, it would be most helpful. Thank you
