Handontable not showing more than 5 columns

Question

I used colHeaders property to set headers. but only first five are visible until I paste data of more than 5 columns code:

 var dataPrePop =["1","2","3","4","5","6","7","8"]
 var container = document.getElementById('example');
 var hot = new Handsontable(container, {
    colHeaders: dataPrePop,  
    contextMenu: true 
 });

Full source code -

var dataPrePop = ["1", "2", "3", "4", "5", "6", "7", "8"]

var container = document.getElementById('example');

var hot = new Handsontable(container, {
  colHeaders: dataPrePop,
  //minSpareCols: 1,
  //minSpareRows: 1,
  //rowHeaders: true,
  //colHeaders: true,
  contextMenu: true
});

body {
  margin: 20px 30px;
  font-size: 13px;
  font-family: 'Open Sans', Helvetica, Arial;
}

a {
  color: #34A9DC;
  text-decoration: none;
}

p {
  margin: 5px 0 20px;
}

h2 {
  margin: 20px 0 0;
  font-size: 18px;
  font-weight: normal;
}

I think this will work for you -

if you want you can set minCols

 minCols: 8 // -- this will do your job

am creating a working sample for you.

var dataPrePop = ["1", "2", "3", "4", "5", "6", "7", "8"]

var container = document.getElementById('example');

var hot = new Handsontable(container, {
  colHeaders: dataPrePop,
  minCols: 8,
  //minSpareCols: 1,
  //minSpareRows: 1,
  //rowHeaders: true,
  //colHeaders: true,
  contextMenu: true
});

body {
  margin: 20px 30px;
  font-size: 13px;
  font-family: 'Open Sans', Helvetica, Arial;
}

a {
  color: #34A9DC;
  text-decoration: none;
}

p {
  margin: 5px 0 20px;
}

h2 {
  margin: 20px 0 0;
  font-size: 18px;
  font-weight: normal;
}

#2 way should be using data

In the below sample createSpreadsheetData(5, 8) handles the number of column and row in the table.

var dataPrePop = Handsontable.helper.createSpreadsheetData(5, 8);

var container = document.getElementById('example');

var hot = new Handsontable(container, {
  data: dataPrePop,
  //minSpareCols: 1,
  //minSpareRows: 1,
  //rowHeaders: true,
  //colHeaders: true,
  contextMenu: true
});

body {
  margin: 20px 30px;
  font-size: 13px;
  font-family: 'Open Sans', Helvetica, Arial;
}

a {
  color: #34A9DC;
  text-decoration: none;
}

p {
  margin: 5px 0 20px;
}

h2 {
  margin: 20px 0 0;
  font-size: 18px;
  font-weight: normal;
}
