### Examples

The following example demonstrates `TableCell.getFormula` in a practical document-editing workflow. It gets the table cell's formula. For each table cell a formula can be defined which is used to calculate the cell's text. The formula can contain references to other table cells in the same table.

function onTxError(error) {
    console.error("TX Text Control error:", error.msg);
    error.handled = true;
}

function inspectFormula(tableCell) {
    tableCell.getFormula(
        function(result) {
            console.log("get formula result:", result);
