Border issue while using colSpan

[adnan1515]

Tried this,
{ table:{ widths:['50%','50%'], body:[[{},{border:[], text:''}], [{border:[],colSpan:2, text:''}]] } }

but this does not work, as it generated border at bottom right

Use the attached file to generate a pdf with two tables.
colspan-bug.json

The first table contains a colspan = 3 in the first row, border is set to [false, false, false, true].
Snippet:

{
  {
    "text": "Zeitraum",
    "bold": true,
    "alignment": "center",
    "border": [
      false,
      false,
      false,
      true
    ],
    "colSpan": 3
  },
  { },
  { }
}

resulting in:

The second table has no column span.
Snippet:

{
  {
    "text": "Zeitraum",
    "bold": true,
    "alignment": "center",
    "border": [
      false,
      false,
      false,
      true
    ],
  },
  {
    "text": "",
    "bold": true,
    "alignment": "center",
    "border": [
      false,
      false,
      false,
      true
    ],
  },
  {
    "text": "",
    "bold": true,
    "alignment": "center",
    "border": [
      false,
      false,
      false,
      true
    ]
  }
}
