I have dashboards with mainly tables and pivot table results. I’d like to add column and row indexes, so when the tables are copied into a doc / presentations, they have these labels included.
For example, each column would have A, B, C… and rows would be numbered 1, 2, 3 … and so on. I’d like for these indexes to be white font on black background…
I’m not sure I’m visualizing what you are describing correctly but you should be able to update the field names on your tables and the background and font colours in the display settings in Properties menu.
You can also update the field name from the dataset layer:
