'targets' in columnDefs of Datatable

abhijitghate

The documentation tells us the way we can use 'targets' in columnDefs. But is there any way we can use it dynamically? For example, I have a global array (containing column numbers) which I update every time certain function is carried out on datatable. I want to render those columns in the global array in a particular fashion. I need to know if there is any way in which I could do this.

"columnDefs":[
{
"targets": hide_them,//name of the global array
"render": //some function
}
]

Not quite like that - with the above, the hide_them array is evaluated only at intialisation time. You'd need to destroy and recreate the table to target different columns. Some operations can be done via the API - changing column visibility at run time for example. But changing the renderer for a column after initialisation is not possible at this time.
