Hello Yisrael. Thanks, but I already had tried it, and it return just a column. Take a look in my code:

wixData.query("Data")
  		.find()
  		.then((results) => {
		  	const uniqueIdNumber= getuniqueIdNumber(results.items);   
		  	$w("#table2").rows = buildRows(uniqueIdNumber); 
 		});
  	function getuniqueIdNumber(items) {    
    		const idNumberOnly = items.map(item => item.idnumber);
      		return [...new Set(idNumberOnly )];
      		
	}
	function buildRows(uniqueData) {   
		return uniqueData.map(curr => {
			return {"name": curr, "city": curr, "idnumber": curr};
		});
	}

My table appears like that:
| NAME | REGION | CITY |
| 123 | 123 | 123 |
| 321 | 321 | 321 |
| 456 | 456 | 456 |

Please, help me. I just need it to conclude my work. Thanks.
