AddRow Error Hep me

[OlottSoft]

My source:

function addRow() {
    var rowData = [{ rivername: '', organizationname: '', regdate: '', useyn:'1', riverseq:'', orgseq:'1' }]; //empty row template
    var rows = grid.getRowsByClass({ cls: 'pq-row-edit' });
    if (rows.length > 0) {//already a row currently being edited.
       var rowIndx = rows[0].rowIndx;

        //focus on editor if any
        grid.editFirstCellInRow({ rowIndx: rowIndx });
    }
    else {
        //append empty row in the first row.                           
        rowindex = grid.addRow({ rowIndxPage: 0, rowData: rowData, checkEditable: false });

        //start editing the new row.
        editRow();
    }
}

Help me!!!

Please correct rowData

Code: [Select]

var rowData = { rivername: '', organizationname: '', regdate: '', useyn:'1', riverseq:'', orgseq:'1' }; //empty row template

After correction, the result is the same.
The code is as follows.
Thank you.

    var orgdata = [
        { rivername: '한강', orgseq: '1', regdate: '2020-05-07', useyn:'1', riverseq:'1'},
        { rivername: '영산강', orgseq: '2', regdate: '2020-05-04', useyn:'1', riverseq:'1' }

Please share a jsfiddle so that I can look into it.

Sorry
I don't know how to use jsfiddle.

After debugging, I tried to fix it because the 'i' in line number '4822' in 'pqgrid.dev.js' was undefined.
Can I do this?
Of course, it becomes 'addrow' without problems.

pqgrid.dev.js 
4820     addRowIndx: function(t) {
4821            for (var e, n = this.that, r = n.options.dataModel, i = r.dataUF, o = n.get_p_data(), a = o.length; a--;) e = o[a], e && (e.pq_ri = a);
4822            if (t) ---> changed if(t && i)
4823                for (a = i.length; a--;) delete i[a].pq_ri
4824        },
