I had a simple idea of displaying a message to the customer, I used the HTML code to display the message, it can be typed directly into the cell or the way I did using the new column template options.
<html><h1><marquee><font color="#F5D0A9">Horário de atendimento das 08:00AM as 06:00PM</font></marquee><h1></html>
<marquee direction = "up"> This text will scroll from bottom to top. </marquee>
<marquee direction = "down" width = "250" height = "200" behavior = "alternate" style = "border: solid">
<marquee behavior = "alternate">
This text will skip
</marquee>
</marquee>
