Hello,
I tried to modify resource header for scheduler control as explained in link below.
https://stackblitz.com/edit/angular-dttnyp-jkzb4e?file=app.component.html
I have made some additional changes in the example above where I have just added few more lines in to resource header and that causes misalignment between the header and appointment rows. See the screenshot below for reference. I have highlighted a issue. Let me know if you have any fix for this.
