Is there a way to truncate a project name in a report?

Here is a Project description column example that displays the first 100 characters. If you want the project name, just change {description} to {name}

valueexpression=CONCAT(LEFT({project}.{description},100),"...") valueformat=HTML

displayname=Project Description

The CONCAT is just there to add "..." to the end of the description, that way a user knows that there may be more text that they're just not seeing in the report. You can omit the CONCAT() portion if you choose, so it would just be:

valueexpression=LEFT({description},100).

If you want to get REALLY fancy and only add the "..." when the description is > 100 characters, you'd use this:

valueexpression=IF(LEN({project}.{description})>100,CONCAT(LEFT({project}. {description},100),"..."),LEFT({project}.{description},100))

valueformat=HTML

displayname=Project Description

That being said, I think what you really want is to REMOVE a specific number of characters from the end. I don't know of a straight forward way of doing that.
