    Description copied from interface: TableMapping
    
    Perform table mapping.
    
    Specified by:
    
    mapTables in interface TableMapping
    
    Parameters:
    
    inSpecs - input tables
    
    Returns:
    
    result of processing input tables
    
    Throws:
    
    java.io.IOException
    
    uk.ac.starlink.task.TaskException

protected uk.ac.starlink.table.StarTable makeSubTable(uk.ac.starlink.table.StarTable inTable,
                                                      java.lang.String[] exprTuple)
                                               throws uk.ac.starlink.task.ExecutionException
```
    Creates a table containing the values which are required by the matcher. This typically consists of a few of the columns from the input table, but in general may come from any JEL expression based on them. Because JEL compilation is performed here, an exception (rethrown as an ExecutionException) may occur.
    
    Parameters:
    
    inTable - input table
    
    exprTuple - array of JEL expressions giving the values of the tuple elements required for the matcher
    
    Returns:
    
    table containing only a column for each tuple element required for the matcher
    
    Throws:
    
    uk.ac.starlink.task.ExecutionException - if a compilation error occurs
