Silly Gridbox[] question

I'm trying to format a text box to look like the simplex tableau in the book
we are using.  I can get the Gridbox to put the lines in where I want them,
but I'm having problems with N[].  In some cases, I would like to use N[] on
a matrix to get a decimal representation, but when I do this the output I
get starts using scientific notation?  I can't seem to figure out how to
stop this.  Any help would be appreciated.  The example follows:

In[187]:=
tempM={{1,1,1,0,0,15},{1,2,0,1,0,10},{8,4,0,0,1,32},{-10,-12,0,0,0,0}}
DisplayForm[GridBox[tempM]]
DisplayForm[GridBox[N[tempM]]]
Out[187]=
{{1,1,1,0,0,15},{1,2,0,1,0,10},{8,4,0,0,1,32},{-10,-12,0,0,0,0}}
Out[188]//DisplayForm=
\!\(\*
  TagBox[GridBox[{
        {"1", "1", "1", "0", "0", "15"},
        {"1", "2", "0", "1", "0", "10"},
        {"8", "4", "0", "0", "1", "32"},
        {\(-10\), \(-12\), "0", "0", "0", "0"}
        }],
    DisplayForm]\)
Out[189]//DisplayForm=
\!\(\*
  TagBox[GridBox[{
        {"1.", "1.", "1.", "0.0", "0.0", "15."},
        {"1.", "2.", "0.0", "1.", "0.0", \( .1  e2\)},
        {"8.", "4.", "0.0", "0.0", "1.", "32."},
        {\(\(- .1\) e2\), \(-12. \), "0.0", "0.0", "0.0", "0.0"}
        }],
    DisplayForm]\)


Thanks,
Gerard
