How to put separator line on UITableView to specific section?

Question

I've a UITableView with some sections. I want that just one section had separator lines for rows.

I tried this:

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell { ... if indexPath.section == 1 { cell.separatorInset = UIEdgeInsetsMake(0, 1, 0, 0) // With other values too. } ... return cell }

but nothing happens.

try cell.separatorInset = UIEdgeInsetsZero for all the sections you dont want the separator for so basically if indexPath.section != 1 { cell.separatorInset = UIEdgeInsetsZero } — iOSer

add a custom view of height 1 with width equal to cell width. show in section 1 and hide in else .... also don't forget to hide default separator of tableView. — Abu Ul Hassan

@Augusto - Add 4 extra spaces at the beginning of a line to indent the length of a tab. — Jake

You can create an extension to UITableViewCell:

extension UITableViewCell { func hideSeparator() { self.separatorInset = UIEdgeInsets(top: 0, left: self.bounds.size.width, bottom: 0, right: 0) } func showSeparator() { self.separatorInset = UIEdgeInsets(top: 0, left: 0, bottom: 0, right: 0) } }

So you can use it in tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath)

if indexPath.section == 1 { cell.hideSeparator() } else { cell.showSeparator() }

You know say to me why line not use all width space? The line leave a little blank space of left side.

@Augusto it's default inset for UITableView in iOS. To remove left space set : tableView.separatorInset = .zero

This works, but the x offset of Title HeaderView is seted to 0.

There is no another methods to do it, so you should arrange your header view offsets by code as you need in this case.
