add a row_id as low level parameter in the datagrid parameter #1243

I am using the datagrid to build dasboard on top of a table, a chart.... example :

But in one case, I was stuck when I wanted to launch a javascript (to export charts as svg files) which need an id : it was possible to launch the script with a button component which has an id as low level parameter but not with a datagrid-item.

Describe the solution you'd like

So I customized the handlebar with a simple addition of {#if row_id}}data-row-id="{{row_id}}"{{/if}}, so a data-grid item has the same parameters as a button :

<div class="card-body">
        <div class="datagrid">
            {{#each_row}}
                 <div class="datagrid-item" {{#if row_id}}data-row-id="{{row_id}}"{{/if}}>

Perhaps this small addition can be introduce in the standard component to give the users more options when using the datagrid component to design dasboards.
