We have the ability in U15 to total in tables. How do I total the highlighted cells in the table below?

  • aggregates and totals are indeed in reports, which are not that similar to tables in many ways reports is the whole technology that harvests data and produce a table elements as a result. This doesn't mean that we could not look at introducing simple algebraic capabilities in table elements but this is currently still not possible

    OK thanks. To be honest we haven't seem much need/use for Reports so have not really used them. Have tried but they don't really do what we want so was trying to use tables instead. tables have limited value at the moment as they don't offer the same level of capability as Excel. I will stay with Excel for the time being and add to drawing as required.
