set linesize #
可以设定结果的最大显示宽度（不限于现有窗口宽度），但stata最大只能设到255。

set linesize specifies the maximum width, in characters, of Stata output.  Most commands in Stata do not   respect linesize, because it is not important for most commands.  Most users never need to set linesize, because it will automatically be reset if you resize your Results window.  This is also why there is no permanently option allowed with set linesize.  set linesize is for use with commands such as list and display and is typically used by programmers who wish the output of those commands to be wider or narrower than the current width of the Results window.

我的思路：先把矩阵转成数据集，然后输出到excel或者txt中

感谢斑竹，请发个取款回帖，我来买。

我用的是stataSE14，esttab指令中有一个option是compress，加上之后会减少列之间的间隔，有助于解决问题
（虽是很久之前的帖子了，不过还是答一下以助后人。。）

非常棒，谢谢
