I want to create a custom report which should look something like this in Android:

The number of schools and number of years will be dynamic. I had created this using the Table Layout but since it is very large data it is taking way too much long to display results. I have also tried using Grid Layout but the column spanning is not working there, the result is just coming as all columns with same width. If I try to set the width using GridLayout.params, it only accepts size in pixels so it is visible differently on various devices.

Is there any way i can specify column width in dp or span the column? titleTxtSpecColumn= GridLayout.spec (5,5) is not working, its still displaying as wrap content.

       val gridLayout = findViewById<GridLayout>(R.id.reportgrid)
       var titleRowSpec: GridLayout.Spec
       var titleTxtSpecColumn: GridLayout.Spec
        titleRowSpec= GridLayout.spec(1)
        titleTxtSpecColumn= GridLayout.spec (0,4)
        val tv0 = layoutInflater.inflate(R.layout.gridcell_header, gridLayout, false) as TextView?
        tv0!!.text = getString(R.string.lbl_date)
        tv0.setBackgroundResource(R.drawable.tablerow_border)
        gridLayout.addView(tv0, GridLayout.LayoutParams(titleRowSpec, titleTxtSpecColumn))

        titleTxtSpecColumn= GridLayout.spec (4)
        val tv1 = layoutInflater.inflate(R.layout.gridcell_header, gridLayout, false) as TextView?
        tv1!!.text = getString(R.string.lbl_grade)
        tv1.setBackgroundResource(R.drawable.tablerow_border)
        gridLayout.addView(tv1, GridLayout.LayoutParams(titleRowSpec, titleTxtSpecColumn))

        titleTxtSpecColumn= GridLayout.spec (5,5)
        val tv2 = layoutInflater.inflate(R.layout.gridcell_header, gridLayout, false) as TextView?
        tv2!!.text = getString(R.string.lbl_grade)
        tv2.setBackgroundResource(R.drawable.tablerow_border)
        gridLayout.addView(tv2, GridLayout.LayoutParams(titleRowSpec, titleTxtSpecColumn))
