合並 2 個表以創建 1 個表：R 中的相同行、不同列

Question

我有兩個具有相同行的表，但它們每個都有不同的列。 是否可以將它們合並在一起？ 我正在使用kabbleExtra包來輸出表格。

Democrat    11.8  18.4  14.2   7.1   6.2   4.5 2.1  64.3

我們可以使用 dplyr 合並表：

> df1 %>% rownames_to_column('party') %>% 
+   inner_join(df2 %>% rownames_to_column('party'), by = 'party') %>% column_to_rownames('party')
           18-24 25-34 35-44 45-54 55-64 65-74 75+ Total.x White Latino Asian African-American Other Total.y
Democrat    11.8  18.4  14.2   7.1   6.2   4.5 2.1    64.3  25.2   22.4  10.0              2.2   5.2    65.1
Republican   3.1   5.0   4.0   5.4   5.3   3.5 1.7    28.0  14.4    7.2   2.8              0.4   2.0    26.8
Other        2.0   0.9   1.2   2.1   0.7   0.6 0.2     7.7   2.5    4.1   0.9              0.0   0.6     8.1
Total       17.0  24.3  19.4  14.5  12.2   8.6 4.1   100.0  42.2   33.7  13.7              2.6   7.8   100.0
