How can I remove the space on a table?

I would like to decrease the space between the text field and the tables in the screenshot below.  How do I do this?

Thanks for reaching out to us. The solution to hide the empty elements that are causing the table to expend vertically. 

Inject the CSS code below to your form to reduce the gap:

/* Hide empty question label and first table row*/

.form-matrix-table>tbody>tr:nth-child(1),

#label_104, #label_129, #label_130{

  display: none;

}
