Use the next approach:

dhxLayout = new dhtmlXLayoutObject(“parentId”, “3L”, “dhx_terrace”);
dhxLayout.skinParams.dhx_terrace.cell_pading_min = 1; // border width
dhxLayout.cells(“a”).hideHeader();

skin is very beautiful terrace.
But it needs much better.
Thanks.

Such behaviour for attached components, which usual hide a header: for creating less borders.
