There is an algorythm to avoid table overlapping when the diagram is exported to PNG. If a table overlaps, is relocated to the left n positions. If the table still overlaps, is relocated again to the left n positions. If the table passes the canvas left border, then is relocated in the position n (table.x = n) and stays there. But very often, when the table width is big, overlaps a previous table, and the exported PNG looks very ugly. To avoid this bug we just let the table in its original position. An if block has been added to the end of the placeTableWithoutOverlap function, in the archive: src\pods\toolbar\components\export-button\export-button.business.ts
