I have a table with months of the year as individual columns. Is there any way to create a summary table to calculate the yearly totals. I believe this would be possible in Excel using a horizontal lookup.
It depends on exactly you want to structure the new table, and whether it has to be a separate table.
The simplest would be to use the column Sum feature to calculate the total for each column.
And I would strongly recommend that you have values in a single column, rather than a column for each month. You can still create a view with monthly columns, but yoy sacrifice a huge amount of flexibility by solutions into monthly columns.
The yearly summary table would be a separate table. I’ll look into using the Sum formula for each column, then calculate the yearly totals from that.
Unfortunately, having the values in a single column isn’t feasible since the data is exported from a third-party platform, and there’s limitations on how it can be formatted.
I’ve been playing around with Sum but can’t figure out since Coda doesn’t have horizontal lookup or lookup a column using a string: Reference Column Name with String
