Answer 1

You could use sub here for a base R option:

input = "Table 1.1. Patient Completion Summary"
table_name <- sub("^.*\b(Table \d+(?:\.\d+)*).*$", "\1", input)
table_name

[1] "Table 1.1"

This answer is flexible and makes no assumptions about the table name, other than it be some number, followed by optional dot separator and digit, zero or more times over.
