PPTs failing accessibility test: Missing Table Header

[bob-dlc]

The accessibility checker built into PowerPoint reports that tables are "Missing Table Header" even when I set options to {autoPage:true, autoPageRepeatHeader:true}. The top row of the table indeed acts like a header visually, but not semantically as far as PowerPoint is concerned. As such, the PPTs fail accessibility testing and are inaccessible for users of assistive technologies such as screen readers. Are there workarounds and/or can this be fixed? Thanks.
