{cmd} 在每个标签页中执行 {cmd}，或者如果指定了 [range]，则仅在标签页编号在 [range] 中的标签页中执行。它类似于执行以下操作：:tabfirst
:{cmd}
:tabnext
:{cmd}
etc.{cmd} 可以包含 '|' 以连接多个命令。{cmd} 不得打开或关闭标签页，也不得重新排序标签页。另请参见 :windo、 :argdo、 :bufdo、 :cdo、 :ldo、 :cfdo 和 :lfdo。:set tabline=%!MyTabLine()然后定义 MyTabLine() 函数以列出所有选项卡页面标签。 一种方便的方法是将其分成两部分：首先遍历所有选项卡页面，并为它们定义标签。 然后获取每个选项卡页面的标签。
function MyTabLine()
let s = ''
for i in range(tabpagenr('$'))
" select the highlighting
if i + 1 == tabpagenr()
let s ..= '%#TabLineSel#'
else
let s ..= '%#TabLine#'
endif
" set the tab page number (for mouse clicks)
let s ..= '%' .. (i + 1) .. 'T'
" the label is made by MyTabLabel()
let s ..= ' %{MyTabLabel(' .. (i + 1) .. ')} '
endfor
" after the last tab fill with TabLineFill and reset tab page nr
let s ..= '%#TabLineFill#%T'
" right-align the label to close the current tab page
if tabpagenr('$') > 1
let s ..= '%=%#TabLine#%999Xclose'
endif
return s
endfunction现在，将为每个选项卡页面调用 MyTabLabel() 函数以获取其标签。function MyTabLabel(n) let buflist = tabpagebuflist(a:n) let winnr = tabpagewinnr(a:n) return bufname(buflist[winnr - 1]) endfunction这只是一个简单的示例，它会生成类似于默认选项卡页面行的选项卡页面行，但不会为修改的缓冲区添加“+”，也不会截断名称。 当没有足够的空间时，您需要以一种巧妙的方式减少标签的宽度。 请查看选项 'columns' 以获取可用空间。
:set guitablabel=%N\ %f一个类似于默认 'guitablabel' 的示例：显示选项卡页面中的窗口数量，如果存在修改的缓冲区，则显示“+”
function GuiTabLabel()
let label = ''
let bufnrlist = tabpagebuflist(v:lnum)
" Add '+' if one of the buffers in the tab page is modified
for bufnr in bufnrlist
if getbufvar(bufnr, "&modified")
let label = '+'
break
endif
endfor
" Append the number of windows in the tab page if more than one
let wincount = tabpagewinnr(v:lnum, '$')
if wincount > 1
let label ..= wincount
endif
if label != ''
let label ..= ' '
endif
" Append the buffer name
return label .. bufname(bufnrlist[tabpagewinnr(v:lnum) - 1])
endfunction
set guitablabel=%{GuiTabLabel()}请注意，必须在设置选项之前定义函数，否则您会收到有关函数未知的错误消息。
