How to maximize table

Hello,

I don't know how to better maximize a table. I show the example to make myself understood.

1) I have a small table in a page in order to have space for other graphs. In order to maximize it I select the button (marked in red).

2) The result of selecting is the table but it doesn't get bigger. Actually is smaller than the previous table without maximize it (see next picture):

As you can see it doesn't fit all the page in order to see it bigger and properly.

Can anyone help me please?

Thank you very much!
