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" to the column one cells also makes the information flow better when it is read aloud by the screen reader. Using the word "to" to the 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.Shows an example of a good table

Bad Table

This table is more difficult for a visually impaired student to understand:  the column headers are not labeled in the HTML code, the merged cells make the reading order unclear, and the use of dashes and month abbreviations make the information less clear.Shows an example of a bad table
