Bug - Fieldflow table filter not firing when the filter sequence includes the first column

[Christopher-O]

Describe the bug

In fieldflow advanced table filtering
https://wet-boew.github.io/GCWeb/components/wb-fieldflow/advanced-en.html#tblfilter
adding the filter to the first column (column 0) does not work and the filter does not render.

To Reproduce

Steps to reproduce the behaviour:

1. Go to 'https://wet-boew.github.io/GCWeb/components/wb-fieldflow/advanced-en.html#tblfilter'
2. Use example code below which manipulates the example code to move the summary to the first column (0) and try to apply filter, which does not render. But if you change to column 3, it does work as normal

Example

<div class="wb-fieldflow" data-wb-fieldflow='
		{
			"srctype": "tblfilter",
			"noForm": true,
			"source": "#table-filtering-example1",
			"fltrseq": [
				{"column": 0}
			],
			"limit": 3
		}'></div>
</form></div>
