gwt border between columns

i'm developping a smal web applicatio开发者_StackOverflown with gwt and one of my vues containes a table that i programmed with cellTable, but the problem is that the css by default of gwt dosen't make borders between columns

Nb : I find how to make borders but only at the extremities and not inter-columns thanks to the property : "borde-style"

so please could you tell me how can i make borders between the columns of my cellTable ?

By default GWT uses css themes. So you have to find out the css class for table adn specially for cells and there you can change the css.

cellTableObject.setBordered(true); sets the border columnwise also
