Styling PDF file exports

GravityExport gives you full control over the look and feel of PDF file exports. Before the PDF is rendered, an HTML table is constructed:

<table border="0" cellpadding="0" cellspacing="0" id="sheet0" class="sheet0">
   <thead>
      <tr class="row0">
         <th class="column0">Form Field 1</th>
         <th class="column1">Form Field 2</th>
         <th class="column2">Form Field 3</th>
      </tr>
   </thead>
   <tbody>
      <tr class="row1">
         <td class="column0">Entry 1 - Field 1 Value</td>
         <td class="column1">Entry 1 - Field 2 Value</td>
         <td class="column2">Entry 1 - Field 3 Value</td>
      </tr>
      <tr class="row2">
         <td class="column0">Entry 2 - Field 1 Value</td>
         <td class="column1">Entry 2 - Field 2 Value</td>
         <td class="column2">Entry 2 - Field 3 Value</td>
      </tr>
      <tr class="row3">
         <td class="column0">Entry 3 - Field 1 Value</td>
         <td class="column1">Entry 3 - Field 2 Value</td>
         <td class="column2">Entry 3 - Field 3 Value</td>
      </tr>
   </tbody>
</table>

Using the barebones stylesheet that's included with GravityExport, the end result will look as follows:

To customize header columns and rows, you need to create your own CSS file with custom styles that target HTML table element selectors/classes. For example, your custom_stylesheet.css may look as follows:

table.sheet0 {
    font-size: 14px;
    font-weight: bolder;
    table-layout: fixed;
    width: 60%;
}

table.sheet0 th, table.sheet0 td {
    text-align: left;
    border: none;
    padding: 5px 0 5px 0;
}

table.sheet0 tr {
    background-color: white;
}

table.sheet0 tr:nth-child(odd) {
    background-color: #F3F3F3;
}

table.sheet0 th {
    font-size: 15px;
    font-weight: bold;
    color: white;
    background-color: #2D4154;
}

In order for GravityExport to apply these styles, you need to use a custom filter to specify where that file is located:

add_filter( 'gravitykit/gravityexport/pdf/styles', function ( $styles ) {
	$styles[] = '/path/to/your/custom_stylesheet.css';
        
        return $styles;
} );

This will apply styles to PDF exports from all forms. If you want to target a single form, suffix the filter with the form's ID:  'gravitykit/gravityexport/pdf/styles_100'. If you wish to completely override the base styles, change the above code sample to read $styles = '/path/to/your/custom_stylesheet.css';

Once done, your PDF will look as follows:
