gird layout help

Hello I would like to make a grid layout sort of like the one of pinterest.
Here is how my layout looks with image placeholder. i want the each box of the grid to be 220×330. each box will have a picture on top, then below it wil be some buttons.

[code=html]<div class=”table_1″ style=”display:inline;”>

<img src=”http://placehold.it/220×330″/>

</div>
<div class=”table_2″ style=”display:inline;”>
<img src=”http://placehold.it/220×330″ />

</div>
<div class=”table_3″ style=”display:inline;”>
<img src=”http://placehold.it/220×330″/>

</div>
<div class=”table_4″>
<img src=”http://placehold.it/220×330″/>

</div>[/code]

this is the code for the grid which looks like this:

However, once i try to add buttons to the bottom of each image. the boxes move below.

code:

[code=html]<div class=”table_1″ style=”display:inline;”>

<img src=”http://placehold.it/100×200″/><br>
<button>sadff</button><button>sadf</button>

</div>
<div class=”table_2″ style=”display:inline;”>
<img src=”http://placehold.it/100×200″ />
<br><button>sadff</button><button>sadf</button>
</div>
<div class=”table_3″ style=”display:inline;”>
<img src=”http://placehold.it/100×200″/>
<br> <button>sadff</button><button>sadf</button>
</div>
<div class=”table_4″>
<img src=”http://placehold.it/100×200″/>
<br><button>sadff</button><button>sadf</button>
</div>[/code]
