readtable bug - if file has only one line, then readtable throws error ONLY if ReadRowNames = 1

Consider a tab-delimited file with only a header line (no data otherwise)
e.g.
m.txt:
name<tab>age
Then
readtable('m.txt', 'FileType', 'text', 'Delimiter', '\t', 'ReadVariableNames', 1 , 'ReadRowNames', 0)
returns an empty table, like it is supposed to.
However
readtable('m.txt', 'FileType', 'text', 'Delimiter', '\t', 'ReadVariableNames', 1 , 'ReadRowNames', 1)
throws an error.

Bug reports to www.mathworks.com Meanwhile, if this is an issue, a workaround would be try...catch around the call...

cmo, you are correct, thank you for finding this bug. I will make a note to have it fixed. For the time being, you can read in the file with ReadRowNames set to false, and then assign the row names and delete the string variable.
