Working solution for GridViews is here:

You may want to look also here for some advise:

Add table to second sheet of Excel using C#

You may want to use EPPLUS library (free) instead of interop because it has a lot of functionality:

In the example you mentioned, you are NOT creating an Excel (or Excel WorkSheets), instead you are trying to open HTML content in Excel format. That is the reason, even if you have TWO Tables, they will show up in single sheet.

Use Microsoft's OpenXml SDK, through which you can create any number of Sheets and inject data into sheets. Even OpenXml SDK got some minor issues when it comes to Date Type (especially while reading data from Excel sheets). In such a case you can go to any third party Excel automation providers like SpreadSheetGear.
