# Complex table issues

I have a problem with my table. I'm trying to create a table, into a two column document. It is a "complex" table with multiple layer. I'm using booktab and multicol. In the rest of my document, everything is built into the 'class' which is 2 column...

I have a the following problem: file ended while scanning document for multcolumn. Anyone can explain me my issue and how to resolve it ?

Cheers !

• The full error message already gives you the cause of this problem: You forgot a }. The line should actually start as follows: \multicolumn{1}{N}{\textbf{Tests}} &. Nevertheless, the spacing of your cells looks strange, at least in the example I used to compile. To solve this, a MWE including the documentclass and all relevant packages would be needed.

You forgot to put the contents of a multicolumn cell between two braces {}. The first of these errors is this line \multicolumn{1}{N}{\textbf{Tests}} and the same error is repeated in subsequent lines.
