Title: BUGFIX: Replaces sprintf() conversion specification in ColumnWidthCSS to non-locale-aware %F (in order to output correctly CSS percents with decimals)

$DOM->setColumnWidths(); was not working in my French-locale site because the CSS width parameter was being passed with decimals preceded by a period instead of a dot. Changing %f to %F in sprintf() solves the issue.
