How to set this Validate for column?
i use this link , but don't work for me.
You've got a few options.
It DOES work if done correctly and is probably the quickest way do this.
2) A custom column that applies regular expression validation.
You can use/adapt one of these open source projects
3) Write your own custom column.
More complex - but allows you to combine server side and client side validation.
