writeDataTable(wb, sheet, x, startCol = 1, startRow = 1, xy = NULL,
  colNames = TRUE, rowNames = FALSE, tableStyle = "TableStyleLight9",
  tableName = NULL, headerStyle = NULL, withFilter = TRUE,
  keepNA = FALSE, sep = ", ", stack = FALSE, firstColumn = FALSE,
  lastColumn = FALSE, bandedRows = TRUE, bandedCols = FALSE)

Arguments

wb

A Workbook object containing a worksheet.

sheet

The worksheet to write to. Can be the worksheet index or name.

x

A dataframe.

startCol

A vector specifying the starting column to write df

startRow

A vector specifying the starting row to write df

xy

An alternative to specifying startCol and startRow individually. A vector of the form c(startCol, startRow)

colNames

If TRUE, column names of x are written.

rowNames

If TRUE, row names of x are written.

tableStyle

Any excel table style name or "none" (see "formatting" vignette).

tableName

keepNA

If TRUE, NA values are converted to #N/A in Excel else NA cells will be empty.

sep

Only applies to list columns. The separator used to collapse list columns to a character vector e.g. sapply(x$list_column, paste, collapse = sep).

stack

If TRUE the new style is merged with any existing cell styles. If FALSE, any existing style is replaced by the new style.

The below options correspond to Excel table options:

firstColumn

logical. If TRUE, the first column is bold

lastColumn

logical. If TRUE, the last column is bold

bandedRows
