  - populate
```
public boolean populate(IlrDTDataProvider dataProvider)
```
    Populates an existing decision table using a data provider.
    Note that a data provider is designed to fill in a decision table, whose structure (that is, columns) has already been created, with data provided by the given data provider.
    This method will clear the contents of the decision table. The given data provider should provide data according to the table structure.
    
    Parameters:
    dataProvider - The data provider.
    
    Returns:
    True if populating of the table succeeds, and false if populating fails or if the decision table has not been loaded.

  - populate
```
public boolean populate(IlrDTDataProvider dataProvider,
               int rowIndex,
               int columnIndex)
```
    Populates an existing decision table using a data provider starting at rowIndex and columnIndex.
    Note that a data provider is designed to fill in a decision table, whose structure (that is, columns) has already been created, with data provided by the given data provider.
    This method does NOT clear existing data from the decision table. Existing data located at these coordinates are erased by data provided by the data provider. The given data provider should provide data according to the table structure.
    
    Parameters:
    dataProvider - The data provider.
    
    Returns:
    True if populating of the table succeeds, and false if populating fails or if the decision table has not been loaded.
