I have produced the following table with kable package, in RMarkdown.
Here's the dataframe:
structure(list(...1 = c("Catalunya", "PIB", "Demanda interna1", "Demanda externa1", "Espanya", "PIB", "Demanda interna1", "Demanda externa1", "Zona euro", "PIB", "Demanda interna1", "Demanda externa1", "PIB d'Alemanya", "PIB de França", "PIB d'Itàlia", "Internacional", "PIB de la UE-27", "PIB dels EUA", "PIB del Japó"), `2020` = c(NA, -11.9, -7.4, -4.5, NA, -11.2, -9, -2.2, NA, -6.1, -5.57, -0.53, -3.8, -7.5, -9, NA, -5.6, -2.2, -4.3), `2021` = c(NA, 6.2, 3.8, 2.4, NA, 6.4, 5.9, 0.5, NA, 5.6, 4.24, 1.36, 3.2, 6.4, 8.3, NA, 5.7, 5.8, 2.1), `2022` = c(NA, 5.5, 2.7, 2.8, NA, 5.5, 5.12183164381576, 0.378168356184236, NA, 3.6, 3.76, -0.16, 1.8, 2.5, 3.7, NA, 3.5, 1.9, 1.1), `1r 2023` = c(NA, 3.2, 1.1, 2.1, NA, 4.1, 1.3, 2.8, NA, 1.2, 0.63, 0.57, -0.2, 1, 2.1, NA, 1.1, 1.71772942152937, 2), `2n 2023` = c(NA, 2.1, 1.2, 0.9, NA, 2, 2.2, -0.2, NA, 0.5, 0.46, 0.04, 0.1, 1.1, 0.3, NA, 0.4, 2.38237207285343, 1.7), `3r 2023` = c(NA, "2.1", "-", "-", NA, "1.8", "1.6", "0.2", NA, "0.1", "-", "-", "-0.4", "0.7", "0", NA, "0.1", "3", "1.2")), row.names = c("1", "2", "aaaa", "4", "5", "6", "7", "8", "9", "10", "11", "12", "13", "14", "15", "16", "17", "18", "19"), class = c("tbl_df", "tbl", "data.frame"))And the table:
options(knitr.kable.NA = "")kable(p3_5, align = "lrrrrrr", booktabs=TRUE, digits=1, format.args = list(big.mark="."), linesep = "" , caption="Producte interior brut (\\% de variació interanual, llevat dels casos indicats)", escape = FALSE) %>% add_header_above(c("", "Any" = 3, "Trimestre" = 3)) %>% kable_styling(latex_options=c("HOLD_position","scale_down"), bootstrap_options = c("condensed"), position="center") %>% column_spec(1, width="4cm") %>% column_spec(2:7, width="2cm") %>% row_spec(0, bold = T) %>% row_spec(1, background="lightgray") %>% row_spec(5, background="lightgray") %>% row_spec(9, background="lightgray") %>% row_spec(16, background="lightgray") %>% row_spec(19, extra_css = "border-bottom: 1px solid;")Is there any way I can leave the name of column 0 blank, and name of row seven as Demanda interna^1, where 1 is supposed to be superscript?
