Gets or sets the specified column widths as a `string` using Fortran-esque fixed-format specifications.
This is equivalent to the “User-Defined” format specifier for External Data as described in the product
documentation.
Note, however, that regardless of the format specifier all imported columns WILL be interpreted using the
.NET command `double.TryParse()` to support the requirements of the underlying variable data for Table.
In the example below, the line has one integer followed by four exponential data types.
385 8.333333333E-003 9.375000000E-003 3.375000000E-001 0.000000000E+000
The corresponding format is `1i3,4e17.9`
Where:
The first entry is the number of occurrences
The second entry is the format specifier
The third entry is the number of characters of data in the definition(including numeric values (0-9),
the letter 'e' (for instances of scientific notation), and any white space and + or - signs)
The fourth entry is the number of digits after the decimal point.
