次のような余分な行と列をすべて削除して、テーブル構造を最適化する jQuery を作成しています。
- a) 2 つ未満の子要素を含む
- b)重複したコンテナーを含む (
.column
can't have child.column
、.row
can't have child.row
)
それでもうまくいきませんでした。6 つのステップで実行されます (コメントに表示されます)。

ですか?
var selection;
//1. Select all rows and columns
selection = $('#example').find('.row, .column');
//2. Deselect rows and columns with more than 1 child
selection = selection.not('.row:has(div:nth-of-type(2)), .column:has(div:nth-of-type(2))');
//3. Deselect rows and columns that contain cells
selection = selection.not('.row:has(.cell:nth-of-type(1)), .column:has(.cell:nth-of-type(1))');
//4. Remove redundant divs
console.log(selection);
//selection.css('border', '1px yellow solid');//paint them yellow (for testing)
selection.children().first().unwrap();
//5. Select duplicate rows and columns
selection = $('#example').find('.row:has(.row), .column:has(.column)');
//6. Remove redundant divs since first removal
selection.children().first().unwrap();
