swift - table is moving down when change the UISegmentedControl (segcon)

Question

my table has 03 sections, 1) has no row, 2) has no row 3) has 04 segcons. when segcon changed then the data changes then reload the section 03. the issue is when the data is not fill the screen then the table moves down automatically. what i want is, the table will not move down automatically eventhough the data is not enough to fill the screen.

i try to use the footer but no help

self.tableView.tableFooterView = UIView()

media segcon

                let mediaCell: MediaCell = tableView.dequeueReusableCell(withIdentifier: "mediaCell", for: indexPath) as! MediaCell

            mediaCell.showImage(url: self.photoNsurlArray[indexPath.row]!)

            mediaCell.reportButtonProgram.addTarget(self, action: #selector(self.funcToHandleReportButton), for: .touchUpInside)

            let timestampe = funcConvertEpocTimeToDate(timeData: self.timestampsGlobal, atIndex: indexPath.row)

            mediaCell.timestampLabel.text = "\(timestampe)"

            let uid = self.uidkeys[indexPath.row]!
            Utils.getUserDetail(uid: uid) { (user) in

                let displayName = user?[Constants.User.display_name] as? String
                if let name = displayName,!(displayName?.isEmpty)! {
                    mediaCell.timestampLabel.text = "by " + "\(name) on " + "\(timestampe)"
                }
                print("getUserDetail display name: ", displayName)
            }
            returnCell = mediaCell
