There are two methods to create a new data table template:
1. Create New Template, create a new Data Table Template
2. Create A New Version of An Existed Template, modifying an existed Data Table Template and saving as a new version.
"Template" in Excel Server 2008 is not the same as the "Template" in the Excel. The "Template" in Excel Server 2008 refers to a integration of Excel "Template", data fields definitions (Single Field, Multiple Field) and Data Fetchers.
