Input Table:How do I decrease the width of a column?

Hi,

 I was wondering if there is a way to decrease the width of a column. I have attached a screenshot of the submission of one of the forms.  I have circled the extra space that can be seen which I don't want. 

I have already selected shrink field but that didn't change anything. 

Using the code,

.form-matrix-row-headers{
  width: 70px!important;
}

Guide :-How-to-Inject-Custom-CSS-Codes

you can edit the with of your headers.

Unfortunately, we cannot target each row headers to change its width.

Hope this information helps.

Please let us know if we can be of further assistance.
