It seems strange that this problem was never reported. Apparently, GM always inserts a <BR> when you start a new line, even if the new line is just an html tag. In particular, when inserting a table, if you write: <TABLE> <TR> <TD> Some stuff here</TD> <TD> Some other stuff here </TD> </TR> <TR> <TD> Row II Some stuff here</TD> <TD> Row II Some other stuff here </TD> </TR> </TABLE> the resulting format is a mess because GM honors the line breaks after each tag. It is therefore necessary to write everything on one line. This is hard to edit and also creates a problem when copying tables from other source code.
