public void hideRow(int row)

Hide the given row.

参数:

row - Zero-based row number

width

public void width(int c,
                  double width)

Specify the width for the given column. Will autoSize by default.

The maximum column width in excel is 255. The colum width in excel is the number of characters that can be displayed with the standard font (first font in the workbook).

Note: The xml spec specifies additional padding for each cell (Section 3.3.1.12 of the OOXML spec) which will result in slightly less characters being displayed then what is given here.

参数:

c - Zero-based column number

width - The width of the column in character widths

public void value(int r,
                  int c,
                  Object value)

Set the cell value at the given coordinates.

参数:

r - Zero-based row number.

c - Zero-based column number.

value - Cell value. Supported types are String, Date, LocalDate, LocalDateTime, ZonedDateTime and Number implementations. Note Excel timestamps do not carry any timezone information; Date values are converted to an Excel serial number with the system timezone. If you need a specific timezone, prefer passing a ZonedDateTime.
