Handling Date Objects

InfiniteTable can handle dates just like any other data type - make sure you specify type="date" for date columns.
If your date column does not specify a custom formatter or renderer, by default the date will be formatted using the toLocaleDateString method of the date object.
For date columns, make sure you specify column.type="date".
This will ensure that the column is sorted correctly (as per the available sortTypes) and that the default date formatting is applied.
In this example, the birthDate column contains dates and we customized the way they are displayed.
const renderValue = ({ value }: { value: Date }) => { return <b>{value.toISOString().split('T')[0]}</b>; };
If no custom renderValue was specified, the dates would have been formatted using the Date.toLocaleDateString()

Using date strings#

If your dates are not instanceof Date but strings or numbers (timestamps) then it's better not to use the column.type="date" but rather to specify a custom column.type along with sortTypes.
For the case when your dates are not actually dates, but date strings (the same applies to timestamps), you have to define your sorting function.
const sortTypes = { mydatestring: (a: string, b: string) => { // use your preferred date parsing library // to turn a string into date and then compare the two values return new Date(a).getTime() - new Date(b).getTime(); }, };
When then pass the sortTypes to the <DataSource /> component and configure our date column to be of type "mydatestring" (it should match the key you specified in your sortTypes definition).
In this example, the birthDate column contains dates as strings, so we have to define a custom column.type and sort type.
