float **pf is not correct because it is a pointer to pointer to float i.e. dual level pointer while each element of the array table is a pointer to an array of floats...
Code:
x()
{
  float x;      /* x is a variable of type float */
  float *pf;    /* pf is a pointer to float */
  float **ppf;  /* ppf is a pointer to pointer to float */

  pf = &x;      /* pf now points to x */
  ppf = &pf;    /* ppf now points to pf */
}
