print

public static String print(TableHeader rowHeader,
                           Map<String,Function<Object,String>> fieldNameToConverterMap,

print

public static String print(TableHeader rowHeader,
                           Map<String,Function<Object,String>> fieldNameToConverterMap,
                           String sortByField,
                           boolean isDescending,

                           String tempTableName)

Serialize Table to printable string and also export a temporary view to easily write sql queries.

Ideally, exporting view needs to be outside PrintHelper, but all commands use this. So this is easy way to add support for all commands

Parameters:

rowHeader - Row Header

fieldNameToConverterMap - Field Specific Converters

sortByField - Sorting field

isDescending - Order

limit - Limit

headerOnly - Headers only

rows - List of rows

tempTableName - table name to export

Returns:

Serialized form for printing
