Some column headers are showing up in bold

  
Several web pages have columns that contain an IF widget.  Those column headers are displaying in bold even though no style is selected and they are not being used to sort the table.  Why do those columns think they need to be bold and how can I disable that?

Thx.

Although you are not specifically saing the column is bold, the bold is appearing maybe because of css inherit styling.
Check the espace css and the page css...
Or use firebug to inspect the page.

One last aproach is forcing the header text not to be bold (inline css: "font-weight: normal;") -> use this is last case...
