+`XLSX.utils.sheet_add_dom` takes a table DOM element and updates an existing
+worksheet object.  It follows the same process as `table_to_sheet` and accepts
+an options argument:
+

+| :---------- | :------: | :-------------------------------------------------- |
+|`raw`        |          | If true, every cell will hold raw strings           |
+|`dateNF`     |  FMT 14  | Use specified date format in string output          |
+|`cellDates`  |  false   | Store dates as type `d` (default is `n`)            |
+|`sheetRows`  |    0     | If >0, read the first `sheetRows` rows of the table |
+|`display`    |  false   | If true, hidden rows and cells will not be parsed   |

+A small helper function can create gap rows between tables:
+
+```js
+function create_gap_rows(ws, nrows) {
+  var ref = XLSX.utils.decode_range(ws["!ref"]);       // get original range
+  ref.e.r += nrows;                                    // add to ending row
+  ws["!ref"] = XLSX.utils.encode_range(ref);           // reassign row
+}
+
+/* first table */
+var ws = XLSX.utils.table_to_sheet(document.getElementById('table1'));
+create_gap_rows(ws, 1); // one row gap after first table
+
+/* second table */
+XLSX.utils.sheet_add_dom(ws, document.getElementById('table2'), {origin: -1});
+create_gap_rows(ws, 3); // three rows gap after second table
+
+/* third table */
+XLSX.utils.sheet_add_dom(ws, document.getElementById('table3'), {origin: -1});
