So on the left side of the line should be the club name, while the right side of the line is a scrolling marquee with text that varies based on what's going on in the tournament. The trick is making the left side (the cell with the club name) take only as much space as it needs, while the right side should use up the remaining space, in order to give the marquee as much space as possible.
For varying screen widths, this becomes tricky. If the club name cell varies in size (different clubs?), it becomes trickier. And if the marquee is "empty" (no text) at any point, it becomes even trickier.
I would recommend designing this for a specific screen size, and thus specific cell sizes. As an example, I am looking at a screen width of 1280 pixels. After some experimentation, I determined that the club name cell needed to be 565 pixels wide (I used your "cardroom name" cell). Instead of using the cell height/width values, I leave those blank and used the following HTML:
<div style="width: 565px; overflow-x: hidden"><span style="color=#ffffff; font-size: 18pt"><nobr>Welcome to the Franlin Snooker and Social Club</nobr></span><br><span style="color=#ff0080; font-size: 15pt"><nobr>Franklin Poker <season></nobr></span></div>So, that leaves 1280 pixels minus 565 pixels, or 715 pixels for the marquee. Again, instead of using the height/width values of the cell, I leave those blank and use the following HTML:
<div style="width: 715px"><marquee> We hope you had a GREAT game of poker. For more information on all things about the Franklin Poker League. Check out www.facebook.com/franklinpoker for game information, and results.</marquee></div>Of course, this makes it more tedious to modify this layout for different screen sizes, and to account for each of the scenarios you have for each of those cells (different marquee text, for example), but it has the results I think you are after.
