Controlling the Width

I have a 3 column Table layout the table is Width=”900px” an each TD are set to width:”300px” but i have one that td’s showing up as 203px, 403px, and 403px.

When i delete the code for the list category post code “[catlist name=Macro author=yes excerpt=yes thumbnail=yes]” everything go’s back to the way it should be?

how can i control the width of the plugin? I think thats what is over riding my table settings?
