Multiple validation messages for a single cell

[Brian]

Is there any way to have multiple validations for a single cell?  I know expressions can be combined using regex or the validation.from or validation.to properties, but that means the validation messages need to be combined, and as far as I can tell, there's no way to add formatting to the validation.messageTemplate property since it only accepts a string (no HTML, no line breaks or tabs - \n\t).

For example, if I want to add validation to a cell that has a max length and restricts certain special characters, I would want to have:

• 2 separate validations each with their own messageTemplate, OR
• 1 validation with a messageTemplate that can be formatted

The only option I have now is a single message that must be written in a single line of text.  For complex validations, these message can end up being verbose and confusing.

Hello Brian,

I am afraid that currently, the Spreadsheet does not offer the possibility to configure two separate validations for a single cell. Also, the cell validation could non accept conditional and / or templated messages. If you think that such feature will add value to the widget, I would suggest you to log your idea as a feature request on our Feedback portal. Based on the support it receives from the community, we will decide on whether to proceed with its implementation or not.
