Strikethrough for entire row in jtable

Question

I have a JTable that takes their value over a mysql data base. I made several customcolumn renderers in order the JTable to show the data formated as I need them. What I need now is to add some strikethrough over some rows depending if the value on the last cell (5) in each row has a specific string value, (test) for example. The strike through must be in each cell of the row except the last cell (that has the test value). Can it work with the other custom column renderers without anything to mix up?

Thank you!

• why Html, why not use TextAttribute directly
