How is your table implemented? Calculating the sum of a column is not a standard feature in TW, so maybe you're using some plugin?
But (probably) regardless, it should be doable, yes. One idea would be a column at extreme left or right with checkboxes. Instead of selecting, you check the relevant rows, and there is a sum calculated from this. It could work so that the selected titles are added to some list, and the sum is calculated by extracing and summing up the weight from all the listed items. <:-) On Monday, May 31, 2021 at 10:43:34 AM UTC+2 [email protected] wrote: > Hi > perhaps someone can help me with this.
