Without seeing the image it’s impossible for us to investigate whether there are any settings that might help. Generally with readTable() it’s a question of getting the boundary of the search area right, where “right” just means adjusted so it achieves the result you are looking for. You generally need to have the table fully within the search area. It’s possible that the column of icons is throwing it off, and as you’ve found, it may not work to exclude that column via the search area. If you submit a screenshot via the support email address, we’ll be happy to look into whether there is a way to read the table.
You should upgrade to eggPlant 12.1 when it is released later this week. The only mechanism we have to roll out fixes is to release new versions, and we generally only investigate issues if they can be reproduced in the current release.
