how about break one big table to several small tables with the same amount of collums?  You can hide the outer border so the user will think that is one table.

I need some help.  I have a servlet that generates about 150 items and creates an HTML table. It takes about 45 - 60 seconds to run.

First, I would like to create pages with 20 - 30 items per page. I through of a way to do this with JavaScript and DIV tags but we know why that isn't the best solution for multi-browser support and doesn't help with the issue below.

Second, I would like to provide the illusion of speed where as soon as the servlet is done with the first 20 results, throw up the HTML and let the process keep going with the other 130 while the users looks at the first 20.

    I don't think you can do that.  See, the HTML engine in your browser will only start rendering the table on the screen unless it encounters the </table> tag.  I could be wrong but I really don't think there is a way to start displaying a table without having all the table elements and a closing tag.  I would recommend either getting all the elements for the table in advance in a different thread while the user is busy doing something else if this is possible.  Then when the user requests the table all you have to do is just construct your table with the elements that you have already prefetched.
