I created a datafile as follows:

    ESTgrowth = FileNameJoin[{"Filepath", "ESTgrowth"}];
    open = OpenAppend[ESTgrowth];
    Write[open, newdata];  (*"newdata" is a list of data appended to "ESTgrowth" *)
    Close[open];

This `code` appends data stream as follows:

    {-17.071, 137.567, 16.554, 0.65}
    {-16.873, 136.138, 16.934, 0.7}
    {-15.397, 135.738, 16.894, 0.7}
    {-14.7, 135.982, 15.9, 0.6}
 
Then I tried to import the data file to present it using `TableForm[...]`.
Of course, 

    Import[ESTgrowth, "Table"]

would NOT work because the data stream consists of lists of data only. My question is how to automatically put the data stream into the following format:

    { 
      {-17.071, 137.567, 16.554, 0.65},
      {-16.873, 136.138, 16.934, 0.7},
      {-15.397, 135.738, 16.894, 0.7},
      {-14.7, 135.982, 15.9, 0.6}
    }

for `TableForm[...]` to work as expected.
