// Идея компонента: один запрос ищет по всем колонкам сразу, а найденное
// подсвечивается прямо в ячейке тегом mark — иначе в широкой строке
// непонятно, за что она зацепилась. Совпадения считаются отдельно от
// строк: «12 совпадений в 4 строках» честнее одного числа. Переключатель
// прячет несовпавшие строки, но шапка и счётчик остаются на месте.
