Questions concerning Spreadsheet Excel Writer

Dear ladies and gentlemen, I'm using the Excel Spreadsheet Writer Package and I'm quite amazed about its abilities. But I have some questions I couldn't answer myself. - how does the function worksheet::setValidation work? The explanation said: "FIXME: add comments" - I'm trying to get a spreadsheet protected using the function: worksheet::protect. $worksheet->protect('password'); It doesn't work like this. Do I have to put it at a certain position in the code or is there anything special about it? Btw. How can I lock cells? The protect-function's explanation says something about "locked properties". I couldn't find them. - Is there any chance to set the width of a column dynamically to the length of the entry? - Are there plans to implement conditional formatting? I think that it is very useful and worth adding it Already thanks for your answers. With the PEAR-Project your're doing a great job and I wanted to say thanks for making all that stuff available! Have a good time! Johannes
