By default DataDynamic has a plain table look and feel.

You can change the standard L&F by clicking on the "Activate" menu button and select the style you want to use, your choice is saved and reused when restarting DataDynamic.

You can manage table styles on the "Table styles" tab in DataDynamic.

You can import an existing *.ddft file or create a new one from scratch.

One ddtf file stands for one table style group in the selection dialog.

You can style table elements by clicking on the element text after edit has been clicked.

Good practice is to change the "Default for all cells" first to determine the default look for all cells.
