<p>Here <code>invoiceVar.getLicName()[i]</code> displays all the values stored in the array.<a href="https://i.stack.imgur.com/AN14V.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/AN14V.png" alt="Error"></a>
Here <code>Dcp Office</code>, <code>Liquor License</code> and <code>Rangabhoomi</code> are values which are getting displayed from that above array but they are getting displayed in new cells but I want that values in same column one below another.</p>
