Yes, that’s a possible workaround, but it’s really cumbersome because you have to first determine the color code that you want (either in hexadecimal, or by using macros like “red” - which I could not find clearly documented anywhere), then you have to highlight the cells, right-click and open the Cell Properties, and set the background color. By comparison, in Confluence, you just highlight the cells and pick a color from the toolbar.
This looks good. The color picker alone would be a real time-saver. Are there plans for XWiki to upgrade to CK5 sometime?
For an entire row, there are some very limited options built into the XWiki editor. If you highlight a row and look at the Styles drop-down menu in the toolbar, there are options like Active Row (gray), Success Row (green), Info Row (blue), Warning Row (yellow), and Danger Row (red). This is nowhere near as convenient as Confluence’s table highlighting tools, but it can be useful if you’re not needing a lot of different types of colors in your table and are not picky about the specific color used to highlight the row.
