Please Make Your Table Headings Sticky

I often stumble upon large data sets or table layouts across the web. When these tables contain hundreds of rows of content, things become problematic once you start to scroll... Look at that table header disappear! Now, if I scroll all the way down to item #300 (for example) will I remember what each column's data is associated with? If this is my first time looking at this table - probably not.
