A regular expression (shortened as regex or regexp), [1] sometimes referred to as rational expression, [2] [3] is a sequence of characters that specifies a match pattern in text.

For example, +2AG means insertion of AG in the forward strand; A sequence matching the regular expression \-[0-9] + [ACGTNacgtn] + denotes a deletion of one or more bases starting from the next ...

find wildcard expressions and regular expressions. A search matches what you see rendered on the screen and in a print preview. The raw "source" wikitext is searchable by employing the insource parameter. For these two kinds of searches a word is any string of consecutive letters and numbers matching a whole word or phrase.

So your numbers don't end up with commas at the end. Copy just the number columns to a sandbox or a new section of a page. See relevant sections of Help:Table to do so. In source mode editing use "search and replace" to delete trailing spaces. Check the box for "Treat search string as a regular expression". Replace [ \t]+$ with nothing. Then ...
