I want to color the rows of my tableview. But now it is that I need to click on the table or any other element first to get the tableView colored. I use Platform.runLater for adding, deleting and changing something.
For the initialize to get the colors even shown I need to do:
tableView.getColumns().get(3).setVisible(true);
tableView.getColumns().get(3).setVisible(false);

Please try to write a minimal, complete and verifiable example : stackoverflow.com/help/mcve

unrelated to your problem: please learn java naming conventions and stick to them

related, though only general advice (as long as your example it's neither minimal nor standalone, I wont give it a closer look, sry) : a) if you need setVisible(false)/(true) there's something wrong in your setup b) there have been several QAs recently related to conditional row styles, please search the site and apply what you learn from the answers

I researched like the whole stackOverflow and even my teacher at the university couldn't figure out the problem. Of course I need setVisible when I use the updateItem method.

Hi, welcome to Stack Overflow! I've removed the redundant tag from your title, and also removed the blockquote at the end of the post ;)

I want to color the rows of my tableview. But now it is that I need to click on the table or any other element first to get the tableView colored. I use Platform.runLater for adding, deleting and changing something.
For the initialize to get the colors even shown I need to do:
tableView.getColumns().get(3).setVisible(true);
tableView.getColumns().get(3).setVisible(false);

related, though only general advice (as long as your example it's neither minimal nor standalone, I wont give it a closer look, sry) : a) if you need setVisible(false)/(true) there's something wrong in your setup b) there have been several QAs recently related to conditional row styles, please search the site and apply what you learn from the answers
