Instance Method Details

#each ⇒ Object

Calls the given block once for each cell in the Tabulo::Row, passing that cell as parameter. Each "cell" is just the calculated value for its column (pre-formatting) for this Tabulo::Row's source item.

Examples:

table = Tabulo::Table.new([1, 10], columns: %i(itself even?))
row = table.first
row.each do |cell|
  puts cell        # => 1,       => false
end

def each
  @table.column_registry.each do |_, column|
    yield column.body_cell_value(@source)
  end
end

#to_h ⇒ Object

Returns a Hash representation of the Tabulo::Row, with column labels acting as keys and the calculated cell values (before formatting) providing the values.

Examples:

table = Tabulo::Table.new([1, 10], columns: %i[itself even?])
row = table.first
row.to_h  # => { :itself => 1, :even? => false }

Returns:

  • a Hash representation of the Tabulo::Row, with column labels acting as keys and the calculated cell values (before formatting) providing the values.

end

#to_s ⇒ Object

Returns a String being an "ASCII" graphical representation of the Tabulo::Row, including any column headers that appear just above it in the Table (depending on where this Row is in the Table and how the Table was configured with respect to header frequency).
