Returns a table that includes a column reflecting one of the smaller of two specified columns of a specified table, the smaller of a specified value and a specified column, or the smaller of two specified values.
Usage notes
*Case 1: Smaller of two specified columns of a specified table. This is the case if First Column Name or Numeric Value and Second Column Name or Numeric Value both specify a column of Table.
*Case 2: Smaller of a specified value and a specified column. This is the case if one of First Column Name or Numeric Value and Second Column Name or Numeric Value specifies a column of Table and the other specifies a numeric value.
*Case 3: Smaller of two specified values. This is the case if First Column Name or Numeric Value and Second Column Name or Numeric Value both specify a numeric value.
In case 1, the nth cell in the returned column corresponds to the nth cell of the table specified by the argument Table. Each cell of the returned column contains the smaller of the corresponding row's cell in First Column Name or Numeric Value and the cell in Second Column Name or Numeric Value.
In case 2, the nth cell in the returned column corresponds to the nth cell of the table specified by the argument Table. Each cell of the returned column contains the smaller of the corresponding row's cell in the specified column and the specified numeric value.

In the returned table, the column that reflects the smaller value is preceded by copies of all the columns in Table.
