Constructor Details
#initialize(opts = {}) ⇒ Table
Initializes a text table instance using the supplied properties. The Table class supports the following hash attributes:
Header
The string to display as a heading above the table. If none is specified, no header will be displayed.
HeaderIndent
The amount of space to indent the header. The default is zero.
Columns
The array of columns that will exist within the table.
Rows
The array of rows that will exist.
Width
The maximum width of the table in characters.
Indent
The number of characters to indent the table.
CellPad
The number of characters to put between each horizontal cell.
Prefix
The text to prefix before the table.
Postfix
The text to affix to the end of the table.
Sortindex
The column to sort the table on, -1 disables sorting.
