Svelte Table Layout

A dynamic table layout for Svelte, a drop-in replacement for HTML tables that use CSS grid under the hood. It lets you easily style columns and rows even if there are cells with nontrivial colspan & rowspan.

<Table class="my-table">
    <Row style="background: gray">
        <Cell>grey</Cell>
        <Cell>row</Cell>
        <Cell>with no decoration</Cell>
    </Row>
    <Row style="background: pink; border: 1px solid red;">
        <Cell colspan={2}>pink row</Cell>
        <Cell>with red border</Cell>
    </Row>
</Table>

<style>
    /* make all cells that intersect the third column bold */
    :global(.my-table [data-column~='3']) {
        font-weight: bold;
    }
</style>

It also supports colspan=row to make cells span the entire row, and lets you align the columns of two different tables.

<Table bind:computedColumnWidths={columns}>
    <Row>
        <Cell>a-really-long-cell</Cell>
        <Cell>normal-cell</Cell>
        <Cell>xd</Cell>
    </Row>
    <Row>
        <Cell colspan="row">lorem</Cell>
    </Row>
</Table>

<Table {columns}>
    <Row>
        <Cell>a</Cell>
        <Cell>b</Cell>
        <Cell>c</Cell>
    </Row>
    <Row>
        <Cell>d</Cell>
        <Cell>e</Cell>
        <Cell>f</Cell>
    </Row>
</Table>
