# Create an HTML table
```ruby
class HTML {
method _attr(Hash h) {
h.keys.sort.map {|k| %Q' #{k}="#{h{k}}"' }.join
}
method _tag(Hash h, name, value) {
"<#{name}" + self._attr(h) + '>' + value + ""
}
method table(Hash h, *data) { self._tag(h, 'table', data.join) }
method table(*data) { self.table(Hash(), data...) }
}
class Table < HTML {
method th(Hash h, value) { self._tag(h, 'th', value) }
method th(value) { self.th(Hash(), value) }
method tr(Hash h, *rows) { self._tag(h, 'tr', rows.join) }
method tr(*rows) { self.tr(Hash(), rows...) }
method td(Hash h, value) { self._tag(h, 'td', value) }
method td(value) { self.td(Hash(), value) }
}
var header = %w( X Y Z)
var rows = 5
var html = HTML()
var table = Table()
say html.table(
# attributes
Hash(
cellspacing => 4,
style => "text-align:right; border: 1px solid;"
),
# header
table.tr(header.map{|elem| table.th(elem)}...),
# rows
(1..rows).map { |i|
table.tr(
table.td(:(align => 'right'), i),
(header.len - 1).of {
table.td(Hash(align => 'right'), 10000.irand)
}...
)
}...
)
```
