How to create a Feature Table with more than one layer or feature layer with the ArcGIS API

I'm here because I'm having a problem with ArcGIS API (version 3.23) . In creating the attribute table or Feature Table , I can not add more than one layer or feature layer to the table, the code being used is the following:

self.myFeatureTable = new FeatureTable({
    "featureLayer": self.map._layers.Municipios_Faixa_Etaria_shapefile_3637_0,
    "outFields": ["*"],
    "map": map,
    "syncSelection": true,
    "showRelatedRecords": true,
    "showAttachments": true,
    "showGridMenu": true
}, 'featureTable');

self.myFeatureTable.startup();

If anyone can help me thank you!
