Hello,
I am currently try to add new column to multiple handsontable instance. My data source is an array with object like :
[
{
data: "1",
type: "numeric"
}
]
And colHeaders is a simple array :
["Price"]
But when i add element in settings and use updateSettings, the hot display a new column without custom header and with empty reference (prop, col) in cells option function :
return function (row, col, prop) {
// prop & col = null
var colSettings = this.instance.getSettings().columns[col];
return cellProperties;
}
I am trying to create JSFiddle, but it works so if you have any idea, maybe i forget something ?
Tested in version PRO 1.7.1 (0.28.1)
Thanks you 
i think in my project something altered with the updateSettings.
