You are missing the point here... The pattern analysis matches what is
done in psql. So you could do want you want by moving the regex
pattern out of the double quotes for example:
$ pg_dump --table '"tDocuments"*' | grep "CREATE TABLE" | grep tDocuments
CREATE TABLE "tDocuments" (
CREATE TABLE "tDocumentsFiles" (

The fine docs explain the full behavior here, the first paragraph
being especially explicit about the use of double quotes:
