1) Using Excel, managed to create a "table" in a dashboard, and data is showing. When I right-click and select "create Chart" from the table, I get the following error:
java.sql.SQLException: [Microsoft][ODBC Excel Driver] Syntax error (missing operator) in query expression 'Credit Class'.
2) It seems there is no way to delete / remove a table/chart from a dashboard? Looks like the only way is to exit without saving and start over.
