How to hide UITableview cell and white space after hide it - ios

Question

I'm trying to hide a cell from a UITableView. I know that UITableViewCell has a property called hidden but after hide I don't want white space. I want the boxes to be close together. I just want hide only condition result_id == nil || resuld_id == "" and hide a cell according to the condition
Func cellForRowAt
I already hide cell like this:
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: reuseIdentifier) as! Static1vs1Cell
let cellNoMatch = tableView.dequeueReusableCell(withIdentifier: reuseNoMatchIdentifier) as! NoMatchTableViewCell
cell.selectionStyle = .none
cellNoMatch.selectionStyle = .none
cellNoMatch.backgroundColor = .clear
if indexPath.section == 0 {
if currentData.count == 0 {
cellNoMatch.historyLabel.text = "No Match"
return cellNoMatch
}
let ad: HistoryListModel = currentData[indexPath.row] as! HistoryListModel
cell.setUI(md: ad, indexPath: indexPath, is_finish: false)
}else if indexPath.section == 1 {
if finishedData.count == 0 {
cellNoMatch.historyLabel.text = "No Match"
return cellNoMatch
}
let ad: HistoryListModel = finishedData[indexPath.row] as! HistoryListModel
cell.setUI(md: ad, indexPath: indexPath, is_finish: true)
if md.result_id == nil || md.result_id == ""{
cell.isHidden = true
}
}
return cell
}
Func heightForRowAt
I set height = 0
func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
var rowHeight:CGFloat = 50
if currentData.count > 0 {
rowHeight = 95
}
else if finishedData.count > 0 {
let ad: HistoryListModel = finishedData[indexPath.row] as! HistoryListModel
if ad.result_id == nil || ad.result_id == "" {
return 0.0
}
else{
return 95
}
} else if finishedData.count == 0 {
rowHeight = 50
} else if currentData.count == 0 {
rowHeight = 50
}
return rowHeight
}

For example, you need to filter the list of table elements and hide unnecessary.
Create a separate array for filtered items and update the table details.
Use it for table delegates.
NB. This solution requires additional memory, do not use it with a very large number of items.
var fullArray : [String] = [] {
didSet {
setFiltered()
}
}
var filteredArray : [String] = [] {
didSet {
tableView.reloadData() // or use batch update
}
}
let tableView = UITableView()
func setFiltered() {
filteredArray = fullArray.filter({ $0 != "Hidden" })
}
