I want to achieve colspan in header in case of datatable. I have more than 1000 columns and they we will be repeating after certain interval, as in case of pivot solution. Like in case of example at http://pivot.webix.com/, if I move continents to the columns also and then we have 3 level of colspan nesting. How to achieve that in datatable ? Kindly provide the sample code for the same (if would be good, if above mentioned example is quoted).
P.S- I saw the complex header example of datatable, but it was not that helpful.
