I am trying to get the rows to include 2 cols each, and it is working to get 4 rows, but I it places the cols wrong, and I cannot figure out why.. Is there anyone who can help me, and explain why my code doesn't work?

 data() {
    return {
      sortMethod: 1,
      postPerRow: 2,
      rowsAmount: 1,
      column: 'col-md-6',
    }
  },

computed: {
  rows() {
      if (this.postsFilter.length == 1) {
        this.column = 'col';
        this.rowsAmount = 1;
        return this.rowsAmount;
      } else {
        this.rowsAmount = Math.ceil(this.postsFilter.length / this.postPerRow);
        console.log(this.rowsAmount);
        this.column = 'col-md-6';
        return this.rowsAmount;
      }
    },
  },

  methods: {
    postRows(index) {
      return this.postsFilter.slice((index - 1) * this.rows, index * this.rows);
    }
  },
