{
    switch(indexPath.section)
    {
        case 0:
        {

                    return 100;
                }
                    break;

                case 1:
                {
                    return 40;
                }
                    break;

                case 2:
                {
                    return 40;
                }
                    break;

                case 3:
                {
                    return 40;
                }
                    break;

                default:
                {
                    return 15;
                }

            }
        }
            break;

}

As mentioned a cell will always have the same width, if however you wish to indent the content to show a master-detail relationship then use...

- (NSInteger)tableView:(UITableView *)tableView indentationLevelForRowAtIndexPath:(NSIndexPath *)indexPath

An UITableViewCell will always take the full width of the UITableView that is displaying the cell.
