setCanvas with dethpstencil argument in table

[D0N7H4V3]

I noticed that function love.graphics.setCanvas have possible argument "deapthstencil" given in table with arguments
But i didnt find any information about why it need it. My depth buffer work great just with "depth = true" in table and lg.setDepthMode("lequal", true), but i really cant understand how i should use depthstencil argument
I am sorry for possible double post, but i dont find answers.
I dont know how to use stencils by now, but i think i will research for it later, now i just use depthbuffers and its all i need for now
