Itab formation for download to Excel

Question

Hi Friends,
I need to create an excel file from an internal table (say itab) which contains header and lower portion data of excel.
I need to create excel like this:
<b>Vendor : itab-lifnr</b> -spaces- <b>Plant : itab-werks</b>
<b>User Name : itab-usr01</b> - spaces - <b>Date : itab-date</b>
Under above, the column headers for the line items
<b>Vendor</b> -space-  <b>Name</b> -space- <b>Material</b> -space- <b>Mail ID</b> -space- <b>Delivery Status</b>
And here the line items (can be more than one)
<b>itab-lifnr</b> -space- <b>itab-name1</b> -space- <b>itab-matnr</b> -space- <b>itab-email</b> -space- <b>itab-stewn</b>
How to go about it:
- is using con_cret and con_tab the only option ? if so, how should the internal table to be sent to gui_download be declared ?
Advance Thanks
Aadarsh
