bw_table - a nested bw_table shortcode changes the table columns

[bobbingwide]

While testing the Dynamic content block using the [bw_table] rendering to tabulate page, the first page listed didn't have an excerpt and contained multiple [bw_table] shortcodes with the parameter fields=title,status,post_date
This caused the table on the calling page to use the wrong table fields - it should have been fields=title,excerpt.

The calling page was Blog, post ID 1433 ( https://s.b/cwiccer/wp-admin/post.php?post=1433&action=edit )

The first page was entitled Future page, post ID 1743 ( https://s.b/cwiccer/wp-admin/post.php?post=1743&action=edit )

The table header is correct but the columns are incorrect.

Writing a hand written excerpt for the Future page resolved the problem

Analysis

• The problem is that the [bw_table] shortcode is not expected to be nested.
• bw_query_table_columns() uses a global called $field_arr which gets overridden by any nested [bw_table] shortcode/block.
