I built a bot that goes to https://www.londonstockexchange.com/indices/ftse-100/constituents/table page, and downloads table from first page to one table variable and then a second table from the second page. Both tables are extracted correctly. Then the bot tries to merge both tables and assign the merged value to the first table. However, after performing the merge, the second table is not appended correctly to the first one. Instead, I got additional empty rows added. This behaviour does not appear, if I firstly save tables to csv files, read back and then try merging.
Is this an expected Data Table Merge behaviour? I did not find any information about this in the documentation.
