<script type="text/javascript" charset="utf-8">
	$(document).ready(function() {
 
		// Define the maximum answers per column
		var maxAnswers = 1;
 
		// Identify this question
		var thisQuestion = $('#question{QID}');
 
		// Index the array columns
		$('table.subquestion-list tr', thisQuestion).each(function(i) {
			$('> *', this).each(function(i) {
				$(this).attr('data-index', i);
			});
		});
 
		// Listener on the checkboxes
		$('input[type="checkbox"]', thisQuestion).on('change', function(e) {
			var thisIndex = $(this).closest('.answer-item').attr('data-index');
			$('[data-index="'+thisIndex+'"] input[type="checkbox"]', thisQuestion).prop('disabled', false);
 
			// If max reached, disable unchecked inputs in this column
			if($('[data-index="'+thisIndex+'"] input[type="checkbox"]:checked', thisQuestion).length >= maxAnswers) {
				$('[data-index="'+thisIndex+'"] input[type="checkbox"]:not(:checked)', thisQuestion).prop('disabled', true);
			}
		});
	});
</script>

The above is the restricted column.



What about Row?

Placing this script in the source of an array-numbers-checkboxes question will enforce a maximum of 3 items checked per row.

<script type="text/javascript" charset="utf-8">
 
	$(document).ready(function() {
 
		// Define the maximum answers per row
		var maxAnswers = 3;
 
		// Identify this question
		var thisQuestion = $('#question{QID}');
 
		// Listener on the checkboxes
		$('input[type="checkbox"]', thisQuestion).on('change', function(e) {
			var thisRow = $(this).closest('tr');
			$('input[type="checkbox"]', thisRow).prop('disabled', false);
 
			// If max reached, disable unchecked inputs in this row
			if($('input[type="checkbox"]:checked', thisRow).length >= maxAnswers) {
				$('input[type="checkbox"]:not(:checked)', thisRow).prop('disabled', true);
			}
		});
	});	
</script>
