DataTables warning: table id=resultadosTable - Incorrect column count. For more information about this error, please see https://datatables.net/tn/18

Description of problem:

I have reviewed all the documentation about this error and I cannot find the solution. The number of fields in the table header corresponds to the data fields, I am not using colspan either.

I am clear that the problem is in the <tr> rows of the "collapse" component but I can't find a way to tell datatables that that part is correct.

thanks for any help

Your codepen shows:

{"a":"foo","b":"bar"}
Many messages, such logging, wow!
Warning, warning!
Oh noes, y u do dis?

And nothing else.

I don't see any code to debug either there or in your message. Can you update it to an example showing the issue please.

fixed..

Thank you. Three of your rows only have a single column in then. Your header and the first row have 7 columns. The others have only 1. Hence they you are correctly getting the error message saying there is a column count mismatch. There is.

To fix make sure all rows have 7 columns.
