It depends where the '_' is put. Whether in "real math mode" or in "math text mode". In your table you have \begin{array}... \textrm{HH}_1 which is ok, as the _1 is outside "math text mode". Then there is \begin{array}... \textbf{\textrm{HH}_1} which is not ok, as the \textbf puts you in text bold mode. A solution would be to use \begin{array}... \mathbf{\textrm{HH}_1} or \begin{array}... \mathbf{\mathrm{HH}_1} You can use the keyboard to type '\mathbf' or Edit->Math->FontChange Andre' -- Those who desire to give up Freedom in order to gain Security, will not have, nor do they deserve, either one.
