Creates an empty table with a column for every "text" based datatype.
This is useful when writing components that have column filters for a variety of text-type columns and you want to ensure the filter can accept all of them.
Usage: feed the output from this component to the input of the component being written, so that the Column Selection filter can be manually configured to accept the required set of text-based data types (e.g. all the numerics, or all the date/time columns)
