I have implemented the ng2 smart table grid for listing

https://akveo.github.io/ng2-smart-table/#/documentation

Here I want to integrate the sorting for 2 columns. For this I used the code

 storeid: {
  title: 'Store #',
  sort: true
},

But this is not numeric sorting. It sorts as 1,10,11... instead of 1,2,3... Is there any example for comparefunction for the particular column.

Please help me.

I'm using the following function to sort a column with text and numbers in it:

compareFunction(direction: any, a: any, b: any) {

  let first = isNaN(Number(a)) ? a.toLowerCase() : Number(a);
  let second = isNaN(Number(b)) ? b.toLowerCase() : Number(b);

  if (first < second || (!isNaN(Number(a)) && isNaN(Number(b)))) {
    return -1 * direction;
  }
  if (first > second || (isNaN(Number(a)) && !isNaN(Number(b)))) {
    return direction;
  }


  return 0;
}

It shows the numbers first (numeric sort) and then the text (1, 2, 10, a, b, c)
