{title:Description}

{pstd}
{opt table} calculates and displays tables of statistics.


{title:Options}

{dlgtab:Main}

{phang}
{opth "contents(table##clist:clist)"} specifies the contents of the table's
cells; if not specified, {cmd:contents(freq)} is used by default.
{cmd:contents(freq)} produces a table of frequencies.
{cmd:contents(mean mpg)} produces a table of the means of the variable
{opt mpg}.  {cmd:contents(freq mean mpg sd mpg)} produces a table of
frequencies together with the mean and standard deviation of variable
{opt mpg}.  Up to five statistics may be specified.

{phang}
{opth "by(varlist:superrowvarlist)"} specifies that numeric or string variables be
treated as superrows.  Up to four variables may be specified in {it:superrowvarlist}.
Note that the {opt by()} option may be specified with the {opt by} prefix.

{dlgtab:Options}

{phang}
{opt cw} specifies casewise deletion.  If {opt cw} is not specified, all
   observations possible are used to calculate each of the specified statistics.
   {opt cw} is relevant only when you request a table containing statistics on
   multiple variables.  For instance, {cmd:contents(mean mpg mean weight)} would
   produce a table reporting the means of the variables {opt mpg} and
   {opt weight}.  Consider an observation in which {opt mpg} is known but
   {opt weight} is missing.  By default, that observation will be used in the
   calculation of the mean of {opt mpg}.  If you specify {opt cw}, the
   observation will be excluded in the calculation of the means of both {opt mpg}
   and {opt weight}.

{phang}
{opt cellwidth(#)} specifies the width of the cell in units of digit widths;
   10 means the space occupied by 10 digits, which is {cmd:0123456789}.  The
   default {opt cellwidth()} is not a fixed number, but a number chosen by
   {opt table} to spread the table out while presenting a reasonable number of
   columns across the page.

{phang}
{opt csepwidth(#)} specifies the separation between columns
   in units of digit widths.  The default is not a fixed number, but a number
   chosen by {opt table} according to what it thinks looks best.

{phang}
{opt stubwidth(#)} specifies the width, in units of digit
   widths, to be allocated to the left stub of the table.  The default is not a
   fixed number, but a number chosen by {opt table} according to what it thinks
   looks best.

{phang}
{opt scsepwidth(#)} specifies the separation between
   supercolumns in units of digit widths.  The default is not a fixed number, but
   a number chosen by {opt table} to present the results best.

{phang}
{opt center} specifies that results be centered in the table's cells.  The
   default is to right-align results.  For centering to work well, you typically
   need to specify a display format as well.  {cmd:center format(%9.2f)} is
   popular.

{phang}
{opt left} specifies that column labels be left-aligned.  The default is to
   right-align column labels to distinguish them from supercolumn labels, which
   are left- aligned.

{phang}
{opt row} specifies that a row be added to the table reflecting the total
   across the rows.

{phang}
{opt col} specifies that a column be added to the table reflecting the total
   across columns.

{phang}
{opt scol} specifies that a supercolumn be added to the table reflecting the
   total across supercolumns.

{phang}
{cmd:format(%}{it:{help fmt}}{cmd:)} specifies the display format for
   presenting numbers in the table's cells.  {cmd:format(%9.0g)} is the default;
   {cmd:format(%9.2f)} and {cmd:format(%9.2fc)} are popular alternatives.  The
   width of the format you specify does not matter, except that {cmd:%}{it:fmt}
   must be valid.  The width of the cells is chosen by {opt table} to present
   the results best.  Option {opt cellwidth()} allows you to override
  {opt table}'s choice.

{phang}
{opt concise} specifies that rows with all missing entries not be displayed.

{phang}
{opt missing} specifies that missing statistics be shown in the table as
   periods (Stata's missing value indicator).  The default is that missing
   entries be left blank.

{phang}
{opt replace} specifies the data in memory be replaced with data
   containing one observation per cell (row, column, supercolumn, and superrow)
   and with variables containing the statistics designated in {opt contents()}.

{pmore}
   This option is rarely specified.  If you do not specify this option,
   the data in memory remain unchanged.

{pmore}
   If you do specify this option, the first statistic will be named {opt table1},
   the second {opt table2}, and so on.  For instance, if
   {cmd:contents(mean mpg sd mpg)} was specified, the means of mpg would be in
   variable {opt table1} and the standard deviations in {opt table2}.

{phang}
{opt name(string)} is relevant only if you specify {opt replace}.
   {opt name()} allows changing the default stub name {opt replace} uses to name
   new variables associated with the statistics.  If you specify
   {cmd:name(stat)}, the first statistic will be placed in {opt stat1}, the
   second in {opt stat2}, and so on.
