Basically, the content type is specified for the whole column with the help of method setColTypes().

mygrid = new dhtmlXGridObject('gridbox');
mygrid.setColTypes("ro,ed,ch");
...
mygrid.init();

But if you need, you may set the type for a specific row or cell, doesn't matter which type the related column has ( methods setCellExcellType() and setRowExcellType(), both in PRO version).
