Hi,
Could you please show us, how exactly do you perform the drag&drop operation? For example, post a screenshot of the recording table.
The problem is, that there is no "table" or "cells" to track. There is a number of divs, mimicking the table, where "cells" are mimicked by vertical "tabs"
What you need to do, in case you want to drop something to "cell" belonging to 17:00 column, is to first detect the child index of header cell 17:00 (childindex=17). And then find vertical tab with the same childindex.
Here is the xpath to detect the header cell "17:00", from which you need to take the childindex value and store it in variable (e.g. varCelIndex):
/dom[@domain='test2.mywebroster.com']//div[#'pane_2']//div[@class='header-container']/div[@innertext='17:00']
And here is the xpath to detect the cell split bar belonging to cell "17:00"
/dom[@domain='test2.mywebroster.com']//div[#'pane_2']//div[@class='body-container']/div[@Childindex=$varCelIndex]
Of course, you can completely skip the part where you detect childindex od header cell and simply insert "17 in repo xpath, but I personally don't like such hardcoded approach. It's always better to detect element based of the label or another identification attribute, either directly from the element in question or its ancestor or sibling.
Once the appropriate "cell" is detected, you may need to release the mouse not directly over the split element, but rather on the split bar + few pixels position? But this may need some tests
