Calls the given block once for each column in the row and returns the corresponding cell as parameter, giving access to its raw value, content and coords attributes

require "tablo"
table = Tablo::Table.new(["a", "b", "c"]) do |t|
  t.add_column("Char", &.itself)
  t.add_column("String", body_formatter: ->(value : Tablo::CellType) {
    value.as(String).upcase
  }, &.itself.*(5))
end
table.each do |row|
  row.each do |cell|
    print cell.value.to_s, "  ", cell.content, "  ",
      cell.coords.row_index, "  ", cell.coords.column_index, "    "
  end
  puts
end

a  a  0  0    aaaaa  AAAAA  0  1
b  b  1  0    bbbbb  BBBBB  1  1
c  c  2  0    ccccc  CCCCC  2  1

Returns a Hash representation of the row, with column label acting as key and the associated cell as value.

require "tablo"
table = Tablo::Table.new(["a"]) do |t|
  t.add_column("Char", &.itself)
  t.add_column("String", body_formatter: ->(value : Tablo::CellType) {
    value.as(String).upcase
  }, &.itself.*(5))
end
table.each do |row|
  h = row.to_h
  puts typeof(h)
  print h["String"].value, "  ", h["String"].content, "  ",
    h["String"].coords.row_index, "  ", h["String"].coords.column_index, "\n"
end

Hash(Int32 | String | Symbol, Tablo::Cell::Data)
aaaaa  AAAAA  0  1

Returns a character string in the form of an “Ascii” graphic representation of the row, including the column headers (with title, subtitle and group where appropriate) that appear just above and the footer for the last row.

require "tablo"
table = Tablo::Table.new(["a", "b", "c"],
  title: Tablo::Heading.new("Title", framed: true),
  subtitle: Tablo::Heading.new("SubTitle", framed: true),
  footer: Tablo::Heading.new("Footer", framed: true)) do |t|
  t.add_column("Char", &.itself)
  t.add_column("String", body_formatter: ->(value : Tablo::CellType) {
    value.as(String).upcase
  }, &.itself.*(5))
end
table.each_with_index do |row, i|
  row.to_s.each_line do |line|
    puts "row #{i} -> #{line}"
  end
