Table function needs care
The table function inside the text element seems sloppy and needs care.
It is possible to define a border thickness but not color.
From within the Cell Properties you can now define a border color, but the only way to see it together with the 90'ies style border around it. When removing the border from the Table Properties the border disappears.
The table function is not one of the sexiest features, but it is annoying when a function this simple is not working properly.
You are most certainly right.
The text element table need a lot of improvement…
We need to add this to our roadmap.
We will keep you updated.
