Hi, Paul.

Thanks for reaching out to us. 

When we use a string type column to make links as buttons,

If you use a one line string, it will be limited to 255 characters; 

 if you use multi line string - it will have 65,535 character limit.

Please check out this documentation about our text fields;

The cells will render HTML, so you can wrap links in anchor tags, for example,

<a href="https://www.w3schools.com">Visit W3Schools.com!</a>

this would render in cell as "Visit W3Schools.com!"  as the displayed text, but it will  lead to the link when clicked;

and the other regular text fields will simply be rendered as text;

-

You can also style it, if you add an ID, or a class in my example :

<a href="yourURL" class="customButton">Link Text</a>

You can then add some custom CSS styles to the table, in Customise tab > Custom CSS;

On my example i will make it look like a green button:

.customButton { 
 background-color: #4CAF50;  
border: none; 
 color: white; 
 padding: 15px 32px; 
 text-align: center; 
 text-decoration: none; 
 display: inline-block; 
 font-size: 16px; 
 margin: 4px 2px; 
 cursor: pointer;
}

and it would look like this :

- If the styles are being overridden, perhaps some kind of conflict from your active Theme that has specific styles;

you can try adding !important clause to any CSS properties you need ( or all of them, if that's easier),

and see if this "forces" the styles you need.

So, for example, for white color and forcing our background color ,  we would do :

.customButton { 
 background-color: #4CAF50 !important;  
 color: white !important;

}

Let me know how that seems, and if you have any questions.
