In this Article I’ll show you how to export tables using a js plugin called tableExport.jquery.plugin wich you can download from github.

this plugin allows you to download or export in various formats such as: CSV, DOC, JSON, PDF, PNG, SQL, TSV, TXT, XLS (Excel 2000 HTML format), XLSX (Excel 2007 Office Open XML format), XML (Excel 2003 XML Spreadsheet format), XML (Raw xml).

the installation is fairly simple import the scripts on your website like

To save the generated export files on client side, include in your html code:

<script type="text/javascript" src="libs/FileSaver/FileSaver.min.js"></script>

To export the table in XLSX (Excel 2007+ XML Format) format, you need to include additionally:

<script type="text/javascript" src="libs/js-xlsx/xlsx.core.min.js"></script>

To export the table as a PDF file the following includes are required:

<script type="text/javascript" src="libs/jsPDF/jspdf.min.js"></script>
<script type="text/javascript" src="libs/jsPDF-AutoTable/jspdf.plugin.autotable.js"></script>

To export the table in PNG format, you need to include:

<script type="text/javascript" src="libs/html2canvas/html2canvas.min.js"></script>

Regardless of the desired format, finally include:

<script type="text/javascript" src="tableExport.min.js"></script>

lease keep this include order.

ignoreColumn can be either an array of indexes (i.e. [0, 2]) or field names (i.e. [“id”, “name”]).

  • Indexes correspond to the position of the header elements th in the DOM starting at 0. (If the th elements are removed or added to the DOM, the indexes will be shifted so use the functionality wisely!)
  • Field names should correspond to the values set on the “data-field” attribute of the header elements th in the DOM.
  • “Nameless” columns without data-field attribute will be named by their index number (converted to a string)

To disable formatting of numbers in the exported output, which can be useful for csv and excel format, set the option numbers: output to false.

Set the option excelFileFormat to 'xmlss' if you want to export in XML Spreadsheet 2003 file format. Use this format if multiple tables should be exported into a single file. Excel 2000 html format is the default excel file format which has better support of exporting table styles.

The excelstyles option lets you define the css attributes of the original html table cells, that should be taken over when exporting to an excel worksheet (Excel 2000 html format only).

To export in XSLX format protobi/js-xlsx forked from SheetJS/js-xlsx is used. Please note that the implementation of this format type lets you only export table data, but not any styling information of the html table.

For jspdf options see the documentation of jsPDF and jsPDF-AutoTable resp.

There is an extended setting for jsPDF option 'format'. Setting the option value to 'bestfit' lets the tableExport plugin try to choose the minimum required paper format and orientation in which the table (or tables in multitable mode) completely fits without column adjustment.

Also there is an extended setting for the jsPDF-AutoTable options 'fillColor', 'textColor' and 'fontStyle'. When setting these option values to 'inherit' the original css values for background and text color will be used as fill and text color while exporting to pdf. A css font-weight >= 700 results in a bold fontStyle and the italic css font-style will be used as italic fontStyle.

When exporting to pdf the option outputImages lets you enable or disable the output of images that are located in the original html table.

Optional html data attributes

(can be applied while generating the table that you want to export)

data-tableexport-cellformat

<td data-tableexport-cellformat="">...</td> -> An empty data value preserves format of cell content. E.g. no number seperator conversion
                                               
                                               More cell formats to be come...

data-tableexport-display

<table style="display:none;" data-tableexport-display="always">...</table> -> A hidden table will be exported

<td style="display:none;" data-tableexport-display="always">...</td> -> A hidden cell will be exported

<td data-tableexport-display="none">...</td> -> This cell will not be exported

<tr data-tableexport-display="none">...</tr> -> All cells of this row will not be exported

data-tableexport-msonumberformat

<td data-tableexport-msonumberformat="\@">...</td> -> Data value will be used to style excel cells with mso-number-format (Excel 2000 html format only)
                                                      Examples:
                                                      "\@"       excel treats cell content alway as text, even numbers
                                                      "0"        excel will display no decimals for numbers
                                                      "0\.000"   excel displays numbers with 3 decimals
                                                      "0%"       excel will display a number as percent with no decimals
                                                      "Percent"  excel will display a number as percent with 2 decimals

data-tableexport-value

<th data-tableexport-value=export title>title</th> -> “export title” instead of “title” will be exported <td data-tableexport-value=export content>content</td> -> “export content” instead of “content” will be exported

Thanks to hhurz for forking the original project and enabling us to do more with the plugin.

My experiance

What I’ve done is in a laravel project is this. First of all I’ve added a button. like this:

<button type="button"
             class="btn btn-default btn-xs pull-left mr-1 export_to_pdf"
             id="export_to_pdf"
             value="table-{{ $institution->InstitutionId .'-'. $periodIndex }}"
             onClick="$('#table-{{ $institution->InstitutionId }}').tableExport({type:'pdf',
                     ignoreColumn: [14],
                     jspdf: {orientation: 'l',
                     format: 'a4',
                     margins: {left:10, right:10, top:20, bottom:20},
                     autotable: {styles: {fillColor: 'inherit',
                     textColor: 'inherit'},
                     tableWidth: 'auto'}
                     }
                     });"
    >
        Export to PDF
    </button>
This button had some bootstrap classes and Id and a value with was kinda the id of the table it represents after this I've added a onClick function with the table Id wich I names #table - and the table id in case there are more tables showing on this page and I need to export just the one I needed or the button represented.
Then I've added the tableExport function wich did the fundamental job to export to pdf. i ignored the column 14 with an array, the orientation was landscape, the document format an A4, some margins, and some styles.

The table had some bootstrap classes, an id with the table id.
<table class="table table-striped table-hover" id="table-{{ $institution->InstitutionId }}">

hope that helps you.
