How to find a specific row by values in jQuery datatables?

You can use fnFindCellRowIndexes to find row index holding certain data in given column.

Then you can use cell().data() API method to update the cell.

var table = $('#example').DataTable();

var rowId = $('#example').dataTable()
   .fnFindCellRowIndexes('Angelica Ramos', 0);

table
   .cell(rowId, 0)
   .data('Angelica Ramos (UPDATED)')
   .draw(false);

Please note that you need to include fnFindCellRowIndexes.js in addition to jQuery DataTables CSS/JS files.

See this jsFiddle for code and demonstration.
