I am trying to get our export to PDF. we are using the PhantomJs export option and when we try to use the group by it breaks the report on the export. if I take off the clientRowGroup then the report is fine.

also if I turn off fast render it also gets the report back but it does not group it.

here is the code, and what I am geting back.

DataTables::create([
                'name' => 'rowGroupTable',
                'dataStore' => $this->dataStore('result'),
                'clientRowGroup' => [
                    'groupby' => [
                        'direction' => 'asc',
                        'top' => '<td colspan="999">' . $groupbyTitle . ': {groupby}</td>',
                    ],
                ],
                'cssClass' => [
                    'table' => 'table table-bordered table-striped table-hover'
                ],
                'columns' => $columns,
                'showFooter' => $this->params['sum'],
                'fastRender' => true,
            ]);

With Group By:

Without Group By:

Without fastRender:

We need it to be PhantomJs for this project, so I just changed to use Tables instead of datatables and its working fine.

We are having an issue with data tables with the row detail as well. Is that due to us using PhantomJs?

$columns['{rowDetailData}'] = ['visible' => false,];

        DataTables::create([
            'name' => 'rowDetailTable',
            'dataStore' => $this->dataStore('result'),
            'fastRender' => true,
            'cssClass' => [
                'table' => 'table table-bordered table-striped table-hover'
            ],
            'columns' => $columns,
            'showFooter' => $this->params['sum'],
            'rowDetailData' => function ($row) {
                $html = '';
                $empty = true;
                foreach ($this->params['detailArr'] as $details) {
                    $detail =
                    !$this->dataStore($details['paramName'])->isEmpty()
                    ? $this->dataStore($details['paramName'])->filter($details['instance'], '=', $row['identifier'])
                    : $this->dataStore('inspectionDetails');
                    if (!$detail->isEmpty()) {
                        $empty = false;
                        $html .= ' <h4 class="underlineBold">' . $details['detailname'] . '</h4>' .
                        Table::create([
                            'dataSource' => $this->dataStore($details['paramName'])->filter(
                                $details['instance'],
                                '=',
                                $row['identifier']
                            ),
                            'cssClass' => [
                                'table' => 'tablewidth table-bordered table-striped table-hover',
                                'td' => 'tdcolor'
                            ],
                            'excludedColumns' => [$details['instance']]
                        ], true);
                    }
                }
                $this->params['detailCount'] += 1;
                if (!$empty) {
                    array_push($this->params['detailCountArray'], $this->params['detailCount']);
                    $empty = true;
                }
                return $html;
            },
            'onReady' => "function() {
                let x = getDetails();
                rowDetailTable.on( 'draw', function () {
                    let num = 0
                    x = getDetails();
                    x.forEach(function(i) {
                        let actual = i;
                        KRrowDetailTable.expandRowDetail(actual);
                    })
                    redraw();
                } );
                x.forEach(function(i) {
                    let actual = i;
                    KRrowDetailTable.expandRowDetail(actual);
                })
                redraw();
                // KRrowDetailTable.expandAllRowDetails();
            }",
        ]);

this is the code and its just not working.

If i take out the ON ready it shows the report but none of the rows are open.

Even If I just do

"onReady" => "function() {

    rowDetailTable.on( 'draw', function () {
        KRrowDetailTable.expandAllRowDetails();
    } );
    KRrowDetailTable.expandAllRowDetails();
}",

it still does not work. they wont expand on Phantomjs
