In other words, number = -1 is the same as asking for the last character of the string. A requested position equal to zero or with a value longer than the ...
Note that with row headers you need to use a separate row in the wikitext for the row header cell. Here below is what a table looks like if the data cell wikitext is on the same line as the row header wikitext.
