Hi,
I struggle with a problem for a day now. I would like to display checkboxes in the 0th column.
I got this warning:
DataTables warning: table id=DataTables_Table_0 - Requested unknown parameter '0' for row 0, column 0. For more information about this error, please see http://datatables.net/tn/4
The data comes from javascript source. (Array of objects. Objects for each row.)
For this column (0th) I do not create data, I do not add an attribute in the datasource object . But even if I add, the problem is the same. (I tried putting 'dummy' as data.)
I created columnDef for the column.
This throws the warning:
(It is the same, if i change data, to anything.)
targets: [0],
render: function (data, type, row, meta) {
if(type === 'display'){
data = '<div class="checkbox"><input type="checkbox" class="dt-checkboxes"><label></label></div>';
}
return data;
}
While this does not:
targets: [0],
render: function (data, type, row, meta) {
return '<div class="checkbox"><input type="checkbox" class="dt-checkboxes"><label></label></div>';
}
Any idea would be much appreciated! Thanks!

Hi @matus.mark ,
Both look ok, so it would help if you could link to a running test case showing the issue so we can offer some help. Information on how to create a test case (if you aren't able to link to the page you are working on) is available here.
Cheers,
Colin
Try using the
columns.defaultContentoption for that column, like this:defaultContent: "",Kevin
Thank you kthorngren and colin! Kthorngern's suggestion did the trick!
