adding rows to a table of data by looking in the table

I' m struggling to get something clean and efficient and would like some
help.  Given a set of data in the form:

  

   data ={

  {x1,1, x1,2, .., x1,n},

  {x2,1, x2,2, .., x2,n},

  {:, :, =83, :},

  {xm,1, xm,2, .., xm,n}

 }



where n columns are of fixed width but m rows grow by appending new rows to
the data set.  Exactly what gets appended depends on values of specific data
elements in the data set.  For example, nextRow If[xm,1>0&&xm,2=A3xm,3,{},{}].

    If the nextRow condition is True then appending[data,nextRow] the next
iteration of data should look like:

   

    data ={

   {x1,1, x1,2, .., x1,n},

   {x2,1, x2,2, .., x2,n},

   {:, :, =83, :},

   {xm,1, xm,2, .., xm,n},

   {, , .., }

  }



And so the process goes for some number of steps continuing to add rows to
data.



Thanks for the help,

Mitch
