PivotGrid Customize Exported Excel File

Product PivotGrid for Progress® Kendo UI®

Description

I am playing around with the Excel export of the PivotGrid and would like to know how to:

  1. Add borders to the cells
  2. Change the background color
  3. Align the text of cells that span across several rows to the top

Solution

The PivotGrid triggers its excelExport event that features the generated kendo.ooxml.Workbook. You can use it to accomplich the desired outcome by following the steps below:

  1. Loop the sheet rows and columns
  2. Use the cells.borderTop, cells.borderBottom, cells.borderRight and cells.borderLeft size and color properties to assign the desired border width and color
  3. Use the cells.background property to assign the new color
  4. Check if the cell has a rowSpan greater than 1 and use the cells.verticalAlign property to align the text as needed
    excelExport: function (e) {
        var sheet = e.workbook.sheets[0];
        for (var i = 0; i < sheet.rows.length; i++) {
            for (var ci = 0; ci < sheet.rows[i].cells.length; ci++) {
                var cell = sheet.rows[i].cells[ci];

                // add borders
                cell.borderTop = { color: "black", size: 1 };
                cell.borderRight = { color: "black", size: 1 };
                cell.borderBottom = { color: "black", size: 1 };
                cell.borderLeft = { color: "black", size: 1 };

                // change the cell background
                cell.background == "#dfdfdf" ? cell.background = "#ffffff": cell.background = "#0080ff";

                // align cells top
                if(cell.rowSpan > 1){
                    cell.verticalAlign = "top";
                }                  
            }
        }
    },
