Ext JS EditorGridPanel - How to split cell to show multiple rows

Question

In Ext.grid.EditorGridPanel table how to split a cell to have two or three rows?

Like the below image

Answer 1

I managed to do a kind of rowspan instead of row splitting. IMO it's easier and it looks the same as grid on attached image. Example code:

var grid = new Ext.grid.EditorGridPanel({
    [...],

    // hook up events
    initComponent: function () {
        Ext.grid.GridPanel.prototype.initComponent.call(this);

        this.getView().on('refresh', this.updateRowSpan, this);
        this.getView().on('rowupdated', this.updateRowSpan, this);
    },

    onLayout : function(vw, vh) {
        this.updateRowSpan();
    },

    // set span on rows
    updateRowSpan: function() {
        var columns = this.getColumnModel().config,
            view = this.getView(),
            store = this.getStore(),
            rowCount = store.getCount(),

            column = columns[0], // put propert column index here
            dataIndex = column.dataIndex,

            spanCell = null,
            spanCount = null;
            spanValue = null;

        for (var row = 0; row < rowCount; ++row) {
            var cell = view.getCell(row, 0),
                record = store.getAt(row),
                value = record.get(dataIndex);

            if (spanValue != value) {
                if (spanCell !== null) {
                    this.setSpan(Ext.get(spanCell), spanCount);
                }

                spanCell = cell;
                spanCount = 1;
                spanValue = value;
            } else {
                spanCount++;
            }
        }

        if (spanCell !== null) {
            this.setSpan(Ext.get(spanCell), spanCount);
        }
    },

    // set actual span on row
    setSpan: function(cell, count) {
        var view = this.getView(),
            innerCell = Ext.get(cell.down('*')),
            height = cell.getHeight(),
            width = cell.getWidth();

        cell.setStyle('position', 'relative');
        if (count == 1) {
            innerCell.setStyle('position', '');
            innerCell.setStyle('height', '');
            innerCell.setStyle('height', '');
        } else {
            innerCell.setStyle('position', 'absolute');
            innerCell.setStyle('height', (height * count - cell.getPadding('tb') - innerCell.getPadding('tb')) + 'px');
            innerCell.setStyle('width', (width - cell.getPadding('lr') - innerCell.getPadding('lr')) + 'px');
        }
    }
});

This code changes style of .x-grid3-cell-inner by applying position: absolute and big enough size to cover rows below. Notice that you must also apply some opaque background to make it work. Working sample: http://jsfiddle.net/RpxZ5/8/

I first wrote code for Ext JS 4, if you interested, here is working sample: http://jsfiddle.net/wQSQM/3/
