As a verb it means to postpone,  to put off do to something later. 

For example, let's table the discussion  this discussion until we have all the data. 

Now we also have three useful idioms. Idiom 1: Off the table 

This means not a possibility. Where do you want to go on vacation? 

I don't know but anywhere I have to fly to is  off the table because I can't afford to fly. 

Number 2: To bring to the table That means to contribute. 

You brought a lot to the table on this  project. You had so many good ideas! 

Idiom #3: The tables have turned. Shall we turn it this way? 

No, this isn't literal. This means something  has completely changed direction, something is  

going to be the opposite of what you thought. For  example, a basketball game. One team is crushing  

it, doing so well but then, their best player gets  injured. And they start playing horribly. Well,  

the tables have turned and it looks  like the other team is going to win.
