Repeat Item Number

You can easily auto populate incremental items numbers in repeats using a business rule. In this example Erepeat is the name of the repeat control and Item is the name of the item control inside the repeat. You also need to set 1 as the default value of first repeating Item control directly into your form field as you're designing your form.

if (Erepeat.itemAdded || Erepeat.itemRemoved){
  for(var i = 0; i < Item.value.length; i++) {
    Item[i].value = i+1;
  }
}

Tables

Tables are identical to repeat controls when referenced in business rules. Tables are a grid layout of repeating items. All the rule examples in this chapter that discuss repeats apply also to tables. The one important note is that you cannot explicitly name the repeat control inside your table. The repeat control inside a table is automatically named as <TableName>Repeat. For example a table named Expense automatically has a repeat named ExpenseRepeat. The rule ExpenseRepeat.itemAdded and ExpenseRepeat.itemIndex references an item added to your table and that item's index respectively.
