Smart Report Engine supports two report data sources, which are:
1- Table-based data source (the default data source ): The report is based on one or more MYSQL tables.
2- SQL-based data source: The report is based on a SQL query. You should use this data source if you want to convert some queries to reports.
Usually, the report data source is defined when calling the 'ReportOptions' class constructor. So, If you are creating a table-based report, you need to call this method to define the table(s) you want to use for your report. You can select one or more tables.
