lightning:datatable component - hiding Save and Cancel buttons after inline edit

According to the documentation on <lightning:datatable>, you may find the suppressBottomBar attribute useful:

Specifies whether the inline edit Save/Cancel bottom bar should be hidden.

<lightning:datatable suppressBottomBar="true" ... />

Clearing the draftValues attribute on the lightning:datatable component clears the edited cells and hides the Save and Cancel buttons at the bottom of the table.

e.g.

cmp.find("table-component-id").set("v.draftValues", null);

Thanks to tsalb for pointing me in the right direction.
