Import/Export table including "hidden property" columns/rows

Hello,

I want to export tables, edit the files offline and import them.

The problem:
– CSV and HTML are easy to edit but do not mark hidden cols/rows
– JSON has marked cols/rows but it’s hard to edit (e.g. move rows)

My idea/question:
HTML would be perfect because it is very easy to edit. Is it possible to extend TablePress to export/import html files with additional classes like “hide-column” and “hide-row” (see below) to hide some cols/rows? This would remember hidden parts.

<table>
    <thead>
        <tr>
            <th class="hide-column">Name</th>
            <th>Gender</th>
            <th>Age</th>
        </tr>
    </thead>
    <tbody>
        <tr>
            <td>Foo</td>
            <td>male</td>
            <td>27</td>
        </tr>
        <tr class="hide-row">
            <td>Bar</td>
            <td>male</td>
            <td>32</td>
        </tr>
        ....

Cheers
