HTML Table to Excel (using Excel_Package)

HTML Table to Excel (using Excel_Package)

  
Hello... I have an action that generates dinamically a HTML table <table>... with all the columns and lines needed for that certain moment - depending on search criteria, number of columns can be different (I have dates on columns and articles on lines. Each column shows the stock on that particular date)

Example:
Article |  26-08  |  27-08  |  28-08
0001   |     0      |     0      |      10
0002   |     5      |     0      |      10
0003   |     25    |    20     |      0
?
Because it has dinamic columns, I thought about HTML to create the matrix.
Having this HTML, I export it to Excel using the action ExportToExcel from the component MultiSheetExcel and works fine.
The problem is that now we need to stop using this component and migrate to Excel_Package... and I have no clue how to implement this.
:(
I would like to know if someone had this experience..
Thank you in advance.
