How to create a table with a two-row header - PrawnPDF

I have simple table generated with PrawnPDF that looks like the one below

|h1|h2|h3|h4|
-------------
|d1|d2|d3|d4|
|d1|d2|d3|d4|
|d1|d2|d3|d4|

Generated by the code below

tb = [["h1", "h2", "h3", "h4"],
      ["d1", "d2", "d3", "d4"],
      ["d1", "d2", "d3", "d4"],
      ["d1", "d2", "d3", "d4"]]

table(tb)do
  row(0).font_style = :bold
end

Now the header needs to be made by two rows as below 

|text       |
|h1|h2|h3|h4|
-------------
|d1|d2|d3|d4|
|d1|d2|d3|d4|
|d1|d2|d3|d4|

I have tried to make a subtable and to use it as the header but it does not span all the table. It looks like 

|text       |
|h1|h2|h3|h4|
----------------------
|d1         |d2|d3|d4|
|d1         |d2|d3|d4|
|d1         |d2|d3|d4|

and no row is bold.

Here the code so far

text = make_cell(content: 'text', colspan: 4)
header_array = [[text], ["h1", "h2", "h3", "h4"]]
header = make_table(header_array)

tb = [[header],
      ["d1", "d2", "d3", "d4"],
      ["d1", "d2", "d3", "d4"],
      ["d1", "d2", "d3", "d4"]]

table(tb)do
  row(0).font_style = :bold
end

Any ideas how can I span the header?

PS I'm using prawn version 1.3.0 and prawn-table 0.2.2

Thanks

UPDATE - Based on Florent answer, if you want/need to pass a block to the table.

header_text = [[{content: "Text", colspan: 4}]]
tb = [["h1", "h2", "h3", "h4"],
  ["d1", "d2", "d3", "d4"],
  ["d1", "d2", "d3", "d4"],
  ["d1", "d2", "d3", "d4"]]

table(header_text + tb)do
  row(0).font_style = :bold
  self.header = 2
end

Dit you try to use the header param ?

header_text = [[{content: "Text", colspan: 4}]]
tb = [["h1", "h2", "h3", "h4"],
  ["d1", "d2", "d3", "d4"],
  ["d1", "d2", "d3", "d4"],
  ["d1", "d2", "d3", "d4"]]

table(header_text + tb, header: 2)do
  row(0).font_style = :bold
end
