I need to export 12 columns to excel but it is not exported correctly The query is the following

$consultaSQLExcel = "select codigo_item as 'CODIGO ITEM', nombre_item as ITEM, numero_serie as 'NUMERO SERIE',   tipo_doc_mov_serie_item as  'TIPO DE DOCUMENTO', numero_documento as 'NUMERO DOCUMENTO', nombre_bodega as  BODEGA, disponibilidad_item_serie as DISPONIBILIDAD, integridad_item_serie as INTEGRIDAD, razon_social_cliente   as CLIENTE, razon_social_proveedor as PROVEEDOR, nombres_usuario as 'CREADO POR',fecha_hora_creacion_ultimo_movimiento   as 'FECHA CREACION' from series_items_inventario where contribuyente=" . $idContribuyente;
$this->src('mysql')  ->query($consultaSQLExcel)  ->pipe($this->dataStore('seriesItems'));

In the view

\koolreport\excel\Table::create(array(
        "dataSource" => $this->dataStore("seriesItems"),
));

The code is the following

public function exportExcel()
    {      
        $report = new ReportSeriesItems();
        $report->exportExcel();
        $report->run()->exportToExcel('ReportSeriesItemsExport')
            ->toBrowser("ReportSeriesItemsExport.xlsx");
    }

The code of the ReportSeriesItems class is

 function exportExcel()
    {
$consultaSQLExcel = "select codigo_item as 'CODIGO ITEM', nombre_item as ITEM, numero_serie as 'NUMERO SERIE',   tipo_doc_mov_serie_item as  'TIPO DE DOCUMENTO', numero_documento as 'NUMERO DOCUMENTO', nombre_bodega as  BODEGA, disponibilidad_item_serie as DISPONIBILIDAD, integridad_item_serie as INTEGRIDAD, razon_social_cliente   as CLIENTE, razon_social_proveedor as PROVEEDOR, nombres_usuario as 'CREADO POR',fecha_hora_creacion_ultimo_movimiento   as 'FECHA CREACION' from series_items_inventario where contribuyente=" . $idContribuyente;
$this->src('mysql')  ->query($consultaSQLExcel)  ->pipe($this->dataStore('seriesItems'));
    }

And finally the code of the view that I want to export (ReportSeriesItemsExport.excel.phpl)

<?php

$sheet1 = "SERIES ITEMS";
?>
<div sheet-name="<?php echo $sheet1; ?>">
    <div>
        <?php
            \koolreport\excel\Table::create(array(
                "dataSource" => $this->dataStore("seriesItems"),
            ));
        ?>
    </div>
</div>

NOTE: I have tried with 5 columns and if it works when exporting but with 12 columns it does not work.

KoolReport support if you are able to help me please answer the forum.

Yes, it worked, but why?
