This would be such a helpful addition. To be able to make the header row have vertical text is a huge feature and would be so helpful to large sheets of information. How come this isn't a thing yet? It can be done in Excel, Google Sheets, and other similar programs. I know Smartsheet isn't a true database program, but this should be able to be implemented in this software. This has been on the wish list of customers for 10 years... I can find discussion posts and web searches for this going back to 2014. This request seems to be ignored, most official responses are "Not yet, and maybe in a future update".
