a hash with html-attributes added to the <ts>s created

:method

the actual method invoked on the record to retrieve the value for the column, or false if name is to be used.

:fromat

either a String by which the value is sprinfed, a proc/lambda to which the value is passed or false if no specific formatting is desired.
