Click row selection

Question

I am trying to find the best table to use with my response applications, and at the moment the reaction table offers everything I need (page numbering, server side control, filtering, sorting, footer row).

However, I cannot select a row. There are no examples that show this.

Some of the things I've tried include trying to set className on a row click. But I can not find the caller in eor t. Also, I don't like this approach, because that’s not how the responsive application should do things.

<ReactTable
            ...
            getTrProps={(state, rowInfo, column, instance) => {
                return {
                    onClick: (e, t) => {
                        t.srcElement.classList.add('active')
                    },
                    style: {
                    }
                }
            }}

Multiple lines with checkboxes and select all using hooks useState(). A small implementation is required to adapt to your own project.

    const data;
    const [ allToggled, setAllToggled ] = useState(false);
    const [ toggled, setToggled ] = useState(Array.from(new Array(data.length), () => false));
    const [ selected, setSelected ] = useState([]);

    const handleToggleAll = allToggled => {
        let selectAll = !allToggled;
        setAllToggled(selectAll);
        let toggledCopy = [];
        let selectedCopy = [];
        data.forEach(function (e, index) {
            toggledCopy.push(selectAll);
            if(selectAll) {
                selectedCopy.push(index);
            }
        });
        setToggled(toggledCopy);
        setSelected(selectedCopy);
    };

    const handleToggle = index => {
        let toggledCopy = [...toggled];
        toggledCopy[index] = !toggledCopy[index];
        setToggled(toggledCopy);
        if( toggledCopy[index] === false ){
            setAllToggled(false);
        }
        else if (allToggled) {
            setAllToggled(false);
        }
    };
