I'm trying to sort a FooTable table on a date column which also has null values, outputted as empty strings. I have included moment.js before footable and footable.sorting in my HTML. My null values are displayed and sorted as 01.01.1970. There are no js console errors. Anyone able to point me in the right direction as to how to fix this?
<table class="footable table table-striped" data-sorting="true">
<thead>
<tr>
<th>(...)</th>
<th data-type="date" data-format-string="DD.MM.YYYY">Invoice Date</th>
<th>(...)</th>
</tr>
</thead>
