To open a list in Access Web Datasheet, you must meet the following requirements:
Note This component is installed by default when you install Office 2010.
If one or more of the above requirements are not met, you will see a message indicating that the list will be displayed in Standard view. The settings you specified for the Datasheet view, such as column order, sorting and filtering, and Total row settings, will be applied to the Standard view before the list is displayed. However, settings such as row height, column width and hidden columns, will be ignored.
Note that even if you do not meet all of the above requirements, you will be able to make changes to the Datasheet view. The changes will be saved, and you will be able to see the effect of your changes the next time you use a computer that meets all the software requirements listed above.
