You can take a look at this link where you can see how you can find your purchase code.

The easiest way to do this is via CSS.

If you wish to apply this code to all of your wpDataTables tables, you can put it in “Custom wpDataTables CSS” text area on wpDataTables Settings page,
or if you wish to apply it only on specific pages, you can put it in between style tags in for example html editor bellow tables short codes. E.g.

 .wpDataTablesWrapper table.wpDataTable td, .WpDataTablesWrapper table.wpDataTable th
{ text-align: center !important;}

In this example we align the text in the center of the table, you can change the text align to your desire by changed the word “center” to “left” or “right”.

This usually happens for MySQL-based tables with server-side processing turned on.

Please check if you have a complicated query with JOINs, calculated columns (e.g. ” SELECT mycolumn*2 AS mycolumn2″), or some custom column aliases (e.g. “SELECT mycolumn AS ‘some/weird/name’). If this is the case, please either create a MySQL view (in PHPMyAdmin or similar MySQL DB manager) and build a wpDataTable based on this view.

File that is responsible for rendering link columns is /source/
By opening that file you can see code for creating html anchor element with attribute “target=’_blank'”.
By changing ‘_blank’ value to ‘_self’ will cause link to open in same page instead of new window.

If you like to have invisible columns in filters, that can be achieved by enabling “Filter in form” option in table edit page.
“Filter in form” option will create filters as a separate section from the table and additionally show filters for all hidden columns.
You can choose which column filter will be visible/hidden by unchecking/checking the Add a filter for this column button in the column settings for desired column.
