What's the different between this and this?

Hey as you see, I am asking about what's the different if we created the marker with two ways

Between this

local marker = {} 
marker[source] = createMarker(1234,2134, 32-1, "cylinder", 2, 0, 120, 231, 150) 

and this;

  
local marker = createMarker(1234,2134, 32-1, "cylinder", 2, 0, 120, 231, 150)

well

1st. Marker will be inserted into a table with index "source", maybe triggered from an event.

2nd. marker its the variable for that marker.

Which way is the best in the usage?
