The border of the table is hidden by the div where this table is a child element.

Maybe you should set the border of the div something like

mygrid = $("#mygrid")

$(mygrid[0].grid.bDiv).css(set here the border) - this is the body div

$(mygrid[0].grid.hDiv).css(set here the border) - this is the header div

how can i show the right border of the grid?

I've edited css (adding line: border-right: 1px solid #D4D0C8;  at table.scroll) but it show border only when i resize a column by hand.

Thanks
