nit: I believe you can get by tag name with 'tbody' here, it's clearer.

Done.

You don't need underscore just `function(row) {`

hmm, I think you should change these <tr> class name from {{loop.index0}} to
something like {{tb_value.table_id}}-column-{{loop.index0}}, which the test
columns becomes "test-table-column-0", "test-table-column-2"
This way you don't do these getElementsByxxx to narrow down your target.

It's also clearer on what you are trying to get.

Done.
