To add items in your current order to a table first press "ADD TO TAB"
On the "ADD TO TAB" pop up screen you will see a list of open tabs and free tables. To add the order to a table, select the relevant table from list. BarTab will open up a tab automatically and link it to your chosen table.
The tab that is opened will be default have the same name as the table. So in the screenshot below you can see that a tab called Table 2 is linked to Table 2. This gives you the flexibility to move the tab to a new table if required.
