We can achieve this using a Mustache template with some conditional checks. For example, if I pass the field names as input variables, they will appear in the output; otherwise, they won't. This way, I can use a single template for different email communications.
{{#column1}}<td class="cell" style="{{#column1Bold}}font-weight:bold;{{/column1Bold}}{{#column1TextColor}}color:{{column1TextColor}};{{/column1TextColor}}{{#column1BackgroundColor}}background-color:{{column1BackgroundColor}};{{/column1BackgroundColor}}">{{#url1}}<a href="{{url1}}">{{/url1}}{{value1}}{{#url1}}</a>{{/url1}}</td>{{/column1}}
