remove column numbers and add line to etable

[nkarwowski]

Hello fixest team, Thank you for your awesome package!

1. I wanted to reach out and ask whether it is possible to remove the column numbers in the etable header? I have played around with style.tex and model.format but have been unable to get rid of the numbered header on my own.

2. Also, how can I add a solid black line before the fixed effects section? I am trying to add a line between the adjusted R squared line and before the section that lists the fixed effects at the end.

Thanks so much for any guidance that you can provide!

Best, Nicole

I attached all of the code and dataset I used to build my table in a zipped folder.

Here is the fixest etable code I used and the table it outputs:

fixest::etable(p1, p2, p3, p1u, p2u, p3u, depvar = FALSE, tex=TRUE, digits=3, fitstat=c("my", "n", "ar2"), keep=c("restored", "upstream"), style.tex=fixest::style.tex("aer", line.top ="", var.title = "$\textbf{Panel B: phosphorous}$"), extralines=list("__ "=c(" ", " ", " ", " ", " ", " "), "^^ "=c(" ", " ", " ", " ", " ", " ")))

\begingroup \centering \begin{tabular}{lcccccc} & (1) & (2) & (3) & (4) & (5) & (6)\

Hi,

1. To remove the column numbers in the etable header, you can use the postprocess.tex argument with a custom function. This method works, but there might be more straightforward solutions that I'm not aware of. Here's a function that can help with your specific requirement:

remove_model_numbers <- function(tab) {
    # Remove lines starting specifically with & (1) & (2)
    tab <- gsub("^\\s*& \\(1\\) & \\(2\\).*\n", "", tab, perl = TRUE)
    return(tab)
}

Apply this function in your etable call like so: etable(p1, p2, p3, p1u, p2u, p3u, headers=NULL, ..., postprocess.tex = remove_model_numbers)

2)For adding a solid black line before the fixed effects section, it seems you have it right with fixef.title = "\\midrule" in your style.tex argument.

To have both you can do something like that:

remove_model_numbers <- function(tab) {
    # Remove lines starting specifically with & (1) & (2)
    tab <- gsub("^\\s*& \\(1\\) & \\(2\\).*\n", "", tab, perl = TRUE)
    return(tab)
}

etable(p1, p2, p3, p1u, p2u, p3u, headers=NULL,
               depvar = FALSE,
               tex=TRUE, digits=3, fitstat=c("my", "n", "ar2"), 
               keep=c("restored", "upstream"),
               style.tex=fixest::style.tex("aer", line.top ="",
                                           fixef.title = "\\midrule", #Add mid-rule before fixed-effects
                                           var.title = "$\\textbf{Panel B: phosphorous}$"),
               extralines=list("__ "=c(" ", " ", " ", " ", " ", " "),
                               "^^  "=c(" ", " ", " ", " ", " ", " ")),
       postprocess.tex = remove_model_numbers) # Remove a line that start with &(1)&(2)

Thanks so much for taking the time to respond. This works great! The table is perfect.
