在 Lua 中打印特定键/值对的表格

我有一个外部的 Lua 表格，结构如下：

sgeT = {
  [2535047] = {
  {
      ["account"] = "TG-MCB110105",
      ["exec"] = "/share/home/00288/tg455591/NAMD_2.8b3/NAMD_2.8b3_Linux-x86_64-MVAPICH-Intel-Ranger/namd2",
      ["execEpoch"] = 1305825864,
      ["execModify"] = "Thu May 19 12:24:24 2011",
      ["execType"] = "user:binary",
      ["jobID"] = "2535047",
      ["numCores"] = "128",
      ["numNodes"] = "8",
      pkgT = {
     },
      ["runTime"] = "65125",
      ["sha1"] = "e157dd510a7be4d775d6ceb271373ea24e7f9559",
      sizeT = {
         ["bss"] = "104552",
         ["data"] = "192168",
         ["text"] = "10650813",
      },
      ["startEpoch"] = "1335843433",
      ["startTime"] = "Mon Apr 30 22:37:13 2012",
      ["user"] = "guo",
      },
 },
  [2535094] = {
  {
      ["account"] = "TG-MCB110105",
      ["exec"] = "/share/home/00288/tg455591/NAMD_2.8b3/NAMD_2.8b3_Linux-x86_64-MVAPICH-Intel-Ranger/namd2",
      ["execEpoch"] = 1305825864,
      ["execModify"] = "Thu May 19 12:24:24 2011",
      ["execType"] = "user:binary",
      ["jobID"] = "2535094",
      ["numCores"] = "128",
      ["numNodes"] = "8",
      pkgT = {
     },
      ["runTime"] = "81635",
      ["sha1"] = "e157dd510a7be4d775d6ceb271373ea24e7f9559",
      sizeT = {
         ["bss"] = "104552",
         ["data"] = "192168",
         ["text"] = "10650813",
      },
      ["startEpoch"] = "1335823028",
      ["startTime"] = "Mon Apr 30 16:57:08 2012",
      ["user"] = "guo",
      },
 },

我正在尝试使用以下 Lua 脚本以按如下方式打印 exec 键/值对：

function DeepPrint (e)
   if type(e) == "table" then
       for k,v in pairs(e) do
          if k == "exec" then
            print(k)
            DeepPrint(v)
          end
       end
   else
    print(e)
   end
 end

FileStr = "lariatData-sgeT-2012-05-01_2.lua"
Hnd, ErrStr = io.open(FileStr, "r")
if Hnd then
    dofile(FileStr)
    for Str in Hnd:lines() do
        DeepPrint(sgeT)
    end
Hnd.close()
else
    print(ErrStr, "\n")
end

理想情况下，我想打印数值索引和 exec 值，例如：

2535047 execVal

但是，当我运行代码时什么也没有返回。原来的数字索引不包含在方括号中，但我添加了它们以使文件能够被读取。但是，由于它们不是连续的，我不能像数组一样循环遍历它们，然而我相信这些数字索引可能是我问题的来源。我不确定我的代码有什么问题，但它返回了空值。有没有人可以推荐我如何修复代码，以便我可以得到适当的键和值返回？先感谢大家！！！
