Section 10.3: Frozen Rows and Columns
Frozen rows and columns should be avoided whenever possible. Making a row or column always visible while scrolling can be accomplished through freezing panes. While this feature can be helpful to sighted users, it should be avoided when creating an accessible workbook as it can cause navigation issues for screen reader users. Users should also be alerted of any frozen rows.
