Hello @marimanga,
Our sincerest apology for being delayed to respond. We always recommend opening a support ticket to get a fast reply.
The use-case in your attached screenshot is quite possible with the ninja table. There are two ways to do this.
First, you can take the column data type as HTML, and then in the HTML editor, you can use both the image and text in the same cell.
Second, you will need to make two columns and in one column choose the data type ‘Image/File/Lightbox‘ and upload the images and in another column, take the text that will be along with the images. Finally, in the Image column use Transform Value and place the two-columns Reference Shortcodes together. See here
