Maximum characters in a String in the Table Panel

What is the maximum number of characters that a String cell in a table panel supports? I’m using a table to display some log messages but when the message is “too long”, it doesn’t get displayed in grafana at all. I can’t find documentation on table limitations.

What exactly is your “too long” and how are formatting a value in the panel?
I use table panel for html/base64 encoded images - 200-300kB without any issue,
