Selenium/Editor: How to click on a cell for inline edit

Hi all,

i am currently trying to set up some frontend tests with selenium and can't get selenium to open an editor inline edit.

what i tried is:
1. Scriptexecuter with jQueryselector Click: executor.executeScript("$('#singleCompanyTable tr:first td:eq(12)').click();");
2. Click on WebElement via xPath
3. Also tried the DataTables cell-selector with a click call afterwards.

None of these works. Has anyone an idea how i get selenium to click on that cell?
