Hi,
thanks for your post, and sorry for the trouble.
Unfortunately, I have to disappoint you here. From everything I know, this is not possible. This is not a limitation of TablePress though, but related to a change in the Shortcode handling in WordPress. Basically, Shortcode inside such HTML attributes are disallowed for security reasons.
As an alternative, you could maybe add your own Shortcode with a bit of PHP code (e.g. in your theme’s “functions.php” file):
add_shortcode( 'andy85_img', 'andy85_image_acf_url' );
function andy85_image_acf_url( $atts ) {
return '<img src="' . do_shortcode( '[acf field="' . esc_attr( $atts['field'] ) . '" /]' ) . '" alt="image-1" width="70" height="50" class="alignnone size-full wp-image-2944" /></a>';
}
Then, you can put
[andy85_img field="image" /]
in the table cells.
Regards,
Tobias
