datatable adding scope for accessibility

Topic: datatable adding scope for accessibility

Mike Barlow free asked 4 years ago

I'm developing an app for a customer who requires the app to be accessible (WCAG/508 accessilbity). And one of the requirements is that tables have a "scope" parameter assigned to TH/TD tags. Currently the mdbDatatable2 component renders thus:

<table data-v-2d57c4e6="" class="table table-bordered dataTable table-fixed table-striped">
    <thead data-v-3a77a5d7="" data-v-c34d2574="" class="table-header" data-v-2d57c4e6="">
        <tr data-v-c34d2574="" data-v-3a77a5d7="">
            <th data-v-c34d2574="" data-v-3a77a5d7=""></th>
            <th data-v-c34d2574="" data-v-3a77a5d7="" class="">
                <i data-v-c34d2574="" data-v-3a77a5d7="" class="mdb-datatable-header-hover-icon fas fa-arrow-up"></i> Field Changed 
            </th>
            <th data-v-c34d2574="" data-v-3a77a5d7="" class="">
                <i data-v-c34d2574="" data-v-3a77a5d7="" class="mdb-datatable-header-hover-icon fas fa-arrow-up"></i> Date 
            </th>
            <th data-v-c34d2574="" data-v-3a77a5d7="" class="">
                <i data-v-c34d2574="" data-v-3a77a5d7="" class="mdb-datatable-header-hover-icon fas fa-arrow-up"></i> Site data accessed from 
            </th>
        </tr>
    </thead>
    <tbody data-v-f820cad8="" data-v-c34d2574="" class="" data-v-2d57c4e6="">
        <tr data-v-c34d2574="" data-v-f820cad8="" class="selectable-row grey lighten-4" style="">
            <td data-v-c34d2574="" data-v-f820cad8="" class="text-center" style="padding-top: 1rem; padding-bottom: 0px;">
                <div data-v-5c7d4350="" data-v-c34d2574="" class="form-check" data-v-f820cad8="">
                    <input data-v-5c7d4350="" type="checkbox" class="form-control filled-in form-check-input" value="true" checked="checked">
                    <label data-v-5c7d4350="" class="form-check-label"></label>
                </div>
            </td>
            <td data-v-c34d2574="" data-v-f820cad8="" contenteditable="false" class="">MOTHER'S MAIDEN NAME</td>
            <td data-v-c34d2574="" data-v-f820cad8="" contenteditable="false" class="">31/10/1985 - 05:01:21 - 0500Z</td>
            <td data-v-c34d2574="" data-v-f820cad8="" contenteditable="false" class="">DANVILLE</td>
        </tr>
    </tbody>
</table>

I need to be able to add "scope" parameters to render like this:

<table data-v-2d57c4e6="" class="table table-bordered dataTable table-fixed table-striped">
        <thead data-v-3a77a5d7="" data-v-c34d2574="" class="table-header" data-v-2d57c4e6="">
            <tr data-v-c34d2574="" data-v-3a77a5d7="">
                <th scope="col" data-v-c34d2574="" data-v-3a77a5d7=""></th>
                <th scope="col" data-v-c34d2574="" data-v-3a77a5d7="" class="">
                    <i data-v-c34d2574="" data-v-3a77a5d7="" class="mdb-datatable-header-hover-icon fas fa-arrow-up"></i> Field Changed 
                </th>
                <th scope="col" data-v-c34d2574="" data-v-3a77a5d7="" class="">
                    <i data-v-c34d2574="" data-v-3a77a5d7="" class="mdb-datatable-header-hover-icon fas fa-arrow-up"></i> Date 
                </th>
                <th scope="col" data-v-c34d2574="" data-v-3a77a5d7="" class="">
                    <i data-v-c34d2574="" data-v-3a77a5d7="" class="mdb-datatable-header-hover-icon fas fa-arrow-up"></i> Site data accessed from 
                </th>
            </tr>
        </thead>
        <tbody data-v-f820cad8="" data-v-c34d2574="" class="" data-v-2d57c4e6="">
            <tr data-v-c34d2574="" data-v-f820cad8="" class="selectable-row grey lighten-4" style="">
                <td scope="col" data-v-c34d2574="" data-v-f820cad8="" class="text-center" style="padding-top: 1rem; padding-bottom: 0px;">
                    <div data-v-5c7d4350="" data-v-c34d2574="" class="form-check" data-v-f820cad8="">
                        <input data-v-5c7d4350="" type="checkbox" class="form-control filled-in form-check-input" value="true" checked="checked">
                        <label data-v-5c7d4350="" class="form-check-label"></label>
                    </div>
                </td>
                <td scope="row" data-v-c34d2574="" data-v-f820cad8="" contenteditable="false" class="">MOTHER'S MAIDEN NAME</td>
                <td scope="row" data-v-c34d2574="" data-v-f820cad8="" contenteditable="false" class="">31/10/1985 - 05:01:21 - 0500Z</td>
                <td scope="row" data-v-c34d2574="" data-v-f820cad8="" contenteditable="false" class="">DANVILLE</td>
            </tr>
        </tbody>
    </table>

Short of recoding the mdbdatatable component is there an easier way to add this requirement?

Thanks

Please insert min. 20 characters.

Unfortunately, there is no easy way to do this with this component - it's a great suggestion for us though. The only way I could think of is setting attributes with javascript:

<mdb-datatable-2 ref="table" v-model="data" />

   mounted() {
    this.$nextTick(() => {
      const table = this.$refs.table.$el;
      const rowCells = table.getElementsByTagName('td');
      const headerCells = table.getElementsByTagName('th');
      rowCells.forEach(cell => cell.setAttribute('scope', 'row'))
      headerCells.forEach(cell => cell.setAttribute('scope', 'col'))
    })
  },

It would be a little bit trickier with asynchrouous data - you need to set those attributes after the entire table is loaded. Kind regards, Magdalena
