You're likely getting an error,
Error using table
The RowNames property must contain one name for each row in the table.
It appears you're trying to create a table with 1 column and 2 rows but instead, your table() inputs provide two columns of 1 row of data. Instead, vertically concatenate the two rows of data into 1 column.
table([mean_rgoog; mean_rm], 'VariableNames', {'mean'}, 'RowNames', {'mean_rgoog', 'mean_rm'})
