Instance Method Details

#tableize(options = {}) ⇒ Object

Create a string representation of self in a tabular format if self is an Array of Arrays or an Array of Hashes.

If an Array of Hashes is passed, the headers are assumed from the keys in the first element of the Array, and the header option is ignored. Also, the headers are sorted, unless overridden with options.

General options: ::max_width: Maximum column width, in order to limit wide columns.

Options with Array of Arrays: ::header: Whether or not the first row of data is a header row. Default is

true.

Options with Array of Hashes: ::columns: An Array of keys that define the order of all columns. ::leading_columns: An Array of keys that should be moved to the left side

of the table.  This option is ignored if columns option
is passed.

::trailing_columns: An Array of keys that should be moved to the right side

                  of the table.  This option is ignored if columns option
                  is passed.
