Input table not displaying completely on mobile device.

I am having trouble with the width of the columns for the mobile view. 

Please try the CSS code below:

@media only screen and (max-width: 480px){

th.form-matrix-column-headers {

    min-width: auto !important;

}

.form-matrix-row-headers{

  width: 70px;

}

}
