The table field does not appear formatted in the front end

A tables data is stored in a single custom field as a JSON string in the database like this…
"{"p":{"o":{"uh":1}},"c":[{"p":""},{"p":""}],"h":[{"c":"Title"},{"c":"Title"}],"b":[[{"c":"Value 1"},{"c":"Value 1"}]]}"

If you catch the fields value without an ACF function like get_field(), you get this JSON string returned. To get the data as an array, you have to use get_field().

You could use the following function to decode the JSON string data into the array.

function acf_table_json_decode( $json ) {

	$a = json_decode( $json, true );

	$return = false;

	// IF BODY DATA

	if ( count( $a['b'] ) > 0 ) {

		// IF HEADER DATA

		if ( $a['p']['o']['uh'] === 1 ) {

			$return['header'] = $a['h'];
		}
		else {

			$return['header'] = false;
		}

		// BODY

		$return['body'] = $a['b'];

		// IF SINGLE EMPTY CELL, THEN DO NOT RETURN TABLE DATA

		if (
			count( $a['b'] ) === 1
			AND count( $a['b'][0] ) === 1
			AND trim( $a['b'][0][0]['c'] ) === ''
		) {

			$return = false;
		}
	}

	return $return;
}

To your second request I will reply later.

Version 1.1.8 should enable editing users table data.
Thanks for reporting that issue!
