Good Table Layout vs Bad Table Layout

Good Table

This table is easier to understand when using a screen reader because the column headers are indicated in the html code and the cells are not merged. Adding the word "Week" in column one cells also makes the information flow better when it is read aloud by the screen reader. Using the word "to" in the chapter assignments instead of a dash and spelling out the month in the due date column also make the table more understandable when read by assistive technologies like a screen reader.

Bad Table

This table is more difficult for a blind student to understand because the column headers are not labeled in the HTML code, and the merged cells confuse the reading order and the use of a dash and month abbreviations is not very clear.
