在RMarkdown的kable中设置列名空白及行名上标

• Set the row names column header to blank:
  When generating the table with kable, use the col.names parameter to replace the default row names header with an empty string. Since the row names column becomes the first column when row.names = TRUE, pass a vector starting with "" followed by your data frame's column names.

• Modify the 7th row name with superscript:
  Update the 7th row name of your data frame to include the superscript syntax (use ^1 for LaTeX output or <sup>1</sup> for HTML). Then set escape = FALSE in kable to ensure the superscript renders correctly instead of being treated as plain text.

Example Code #

Assuming your data frame is named my_df:

# Modify the 7th row name (use <sup>1</sup> if outputting to HTML)
rownames(my_df)[7] <- "Demanda interna^1"

# Generate the table with blank row header and rendered superscript
library(knitr)
kable(my_df, 
      row.names = TRUE, 
      col.names = c("", names(my_df)),  # Blank first column header
      escape = FALSE)                   # Allow superscript syntax

Notes #

• If you don’t want to modify the original data frame, create a copy first:

  my_df_temp <- my_df
  rownames(my_df_temp)[7] <- "Demanda interna^1"
  kable(my_df_temp, row.names = TRUE, col.names = c("", names(my_df_temp)), escape = FALSE)
  

• For HTML output, replace ^1 with <sup>1</sup> to get proper superscript formatting.
