从2个不同的阵列加载tableview

if indexPath.row < customerDetails.count
{
    // load from customerDetails array
    let customer = customerDetails[indexPath.row]
}
else
{
   // load from customerDetails2 array
   let customer = customerDetails2[indexPath.row - customerDetails.count]
}

您可以将两者分为两个部分,而不是仅使用一个部分来创建它:

let sections = [customerDetails,customerDetails2]

在numberOfSections中,您可以提供计数:

func numberOfSections(in tableView: UITableView) -> Int {
    return sections.count
}

之后,在numberOfItemsInSection中,您可以根据节号提供相应的数组:

func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return sections[section].count
    }

完成此操作后,您可以轻松访问并向cellForRow提供数据,如下所示:

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {

    let customer = sections[indexPath.section][indexPath.row]
     cell.nameLabel.text = customer.name
}

希望有帮助!!

将cellforRow中的代码更改为此,注意

 let arr1Count = customerDetails.count

  if(indexPath.row < = arr1Count )
 {
     let customers = customerDetails[indexPath.row]
      cell.nameLabel.text = customers.fname
 }
else

{
     let customers = customerDetails2[indexPath.row - arr1Count]
      cell.nameLabel.text = customers.fname

 }
