sublimt text 设置tab宽度为2个空格

设置——设置——在打开的标签（Preferences.sublime-settings-Uer）最下面加上以下两行：

// The number of spaces a tab is considered equal to
"tab_size": 2,
 
// Set to true to insert spaces when tab is pressed
"translate_tabs_to_spaces": true,

推荐使用此配置

{
	"color_scheme": "Packages/Color Scheme - Default/Mariana.sublime-color-scheme",
	"font_size": 19,
	"ignored_packages":
	[
		"Vintage"
	],
	"tab_size": 2,
	"translate_tabs_to_spaces": false,
	//若要在保存时自动把tab 转换成空格，请把下面一行设置成 true，如不需要: 设置成 false
	"expand_tabs_on_save": false,
	"theme": "Adaptive.sublime-theme"
