/**
 * VirtualTable is not crated by <table>, the header cell width cannot auto align the body cell width which has large content.
 * So VirtualTable get the columns widths by following steps:
 * 1. Only render the headers with flex style
 * 2. Get the widths of the table headers in ref
 * 3. Calculate the sticky position of the fixed column/header if exists
 * 4. Render the table body columns with the headers widths gotten in step 2
 *
 * If the Virtual Table is render inside a container with open animation e.g. <Modal />,
 * the colWidths may be calculated during the transition and get the wrong width
 * wrap the getColumnWidths function by useDebounce to get the final correct column widths
