But that should be okay, I can always use sed to remove the ^M characters. Thank you.
I don't see how this code prints out the heading line, but you can get rid of the carriage return characters in the awk script without needing to also invoke sed:
Note that the sample input and output you provided used <space> as a field delimiter but you said your files were <tab> delimited. I specified <tab> as the output field separator here assuming that your real data is <tab> delimited.

DESCRIPTION
Returns a result set listing the index and statistics for a table.
PARAMETERS
o $connection

- The name of the table.
o $unique
- An integer value representing the type of index information to return.
o $0
- Return only the information for unique indexes on the table.
o $1
- Return the information for all indexes on the table.
