Neovim 函数 vim.tbl_deep_extend

用于递归合并表及其值：

local person = {
    name = "joe",
    age = 19,
    skills = {"python", "html"},
}

local someone = {
    name = "siduck",
    skills = {"js", "lua"},
}

local result = vim.tbl_deep_extend("force", person, someone)

-- result 的值：
-- {
--     name = "siduck",
--     age = 19,
--     skills = {"js", "lua"},
-- }
