Where can I find the canvas rules for setting up a rubrics table? The basic "intro to rubrics" doesn't really cover the details I need to know. For example, My rubrics table has five rows by 9 columns. As I input the point values/descriptions, I get to the last column and canvas won't let me fill in the column because I've used to many characters across the row so what is the maximum characters across the row?
Also, is there a way to set each column a specific width?
