Failed Importing the Lib

Try using this lib, but got error:

<script lang="ts">
import { onMount } from 'svelte';
import jspreadsheet from 'jspreadsheet-ce';
import 'jspreadsheet-ce/dist/jspreadsheet.css';

// Global Variables
export let jsprInst: jspreadsheet.JspreadsheetInstance = null;
export let jsprOpts: jspreadsheet.JSpreadsheetOptions = {};

// Local Variables
let tableEl: HTMLDivElement;
let defaultOpts: jspreadsheet.JSpreadsheetOptions = {
    minDimensions: [1000, 100000]
};

onMount(() => {
    jsprInst = jspreadsheet(tableEl, {...defaultOpts, ...jsprOpts});
});

</script>

<div bind:this={tableEl}></div>

Error:

'default' is not exported by node_modules/jspreadsheet-ce/dist/index.js, imported by src/components/jspreadsheet-ce.svelte
    1: <script lang="ts">
    2: import { onMount } from 'svelte';
    3: import jspreadsheet from 'jspreadsheet-ce';
              ^
    4: import 'jspreadsheet-ce/dist/jspreadsheet.css';
    error during build:
    Error: 'default' is not exported by node_modules/jspreadsheet-ce/dist/index.js, imported by src/components/jspreadsheet-ce.svelte
    ...

Any idea what might happened?
Thanks,

Start with src/components/jspreadsheet-ce.svelte and inspect node_modules/jspreadsheet-ce/dist/index.js, focusing on the import/export mismatch shown by the build error. Reproduce the build with this component and confirm that the import resolves without the reported error.
