I'm trying to set some definitions for columns in a table and am reading up on colgroup and col tags.
For colgroup, websites keep on referring to "span" as the definitive way to apply the tag to the column. However, this makes no sense to me.
So let's put it another way:
If I have three columns in a table, and I want a colgroup to affect the third column—farthest from the left—how would I go about doing this?
Please feel free to let me know if I'm grossly getting it wrong, at any point.
