I put in the preamble of the document: "\setlength{extrarowheight}{2pt}" for add extra height (e.g. 2pt) to all cells of all tables. View->pdflatex (or dvi...) don't compiles and gives error: "Undefined control sequence. Latex Error: Missing \begin{document}"
In this case you have to put also this to the document preamble: \usepackage{array} This is automatically added by LyX when setting a fixed table cell width. You also had an error: \setlength{\extrarowheight}{2pt} not \setlength{extrarowheight}{2pt} regards Uwe
