我已经阅读了关于这个错误的所有其他问题。但是我找不到正确的解决方案来修复mysql server 8.0.13的错误。请帮忙。
下表的第255列是mediumtext

但这让我犯了个错误-

Error Code: 1118. Row size too large (> 8126). Changing some columns to TEXT or BLOB may help. In current row format, BLOB prefix of 0 bytes is stored inline

我也尝试过其他的解决方案，比如调整my.ini文件，比如增加innodb\u log\u文件大小到任何程度，比如2g、5g，但这些调整都没有成功。
另外，我不想仅仅关闭innodb\u strict\u模式，因为我不认为关闭验证是唯一的解决方案。mysql server 8.0.13版的任何其他解决方案。

你设计了一个愚蠢的table，已经达到了尺寸限制，对不起！当您有这样的“数组”方案时，您应该进行规范化—sql是为您设计的。
你得把table弄平。而不是 (id, val1, val2, val3, val4, ...) ，你想要什么 (id, 1, val), (id, 2, val), (id, 3, val), ... . 使用这个方案，您不会达到大小限制，并且您有一个更惯用的模式。
你还需要考虑到 status 字段，所以我们最终得到这样的结果：

CREATE TABLE `guidatatable` (
   `id`     INT NOT NULL AUTO_INCREMENT,
   `status` INT NULL,

   PRIMARY KEY (`id`)
) ENGINE=InnoDB;

CREATE TABLE `guidatatable_values` (
   `id`       INT NOT NULL,
   `colNum`   INT NOT NULL,
   `colValue` MEDIUMTEXT NOT NULL,

   PRIMARY KEY (`id`, `colNum`)
) ENGINE=InnoDB;

一定要确保 guidatatable_values.id 外键指的是 guidatatable.id （我一下子就忘了最好的语法）。
数据转换的具体示例；这是：

id  col01   col02   col03   status
 1  Hello   World   !         42
 2  How     Are     You       99
 3  I       Am      Fine      168

变成这样：

id   status
  1   42
  2   99
  3   168

 id   colNum   colValue
  1   1        Hello
  1   2        World
  1   3        !
  2   1        How
  2   2        Are
  2   3        You
  3   1        I
  3   2        Am
  3   3        Fine

如您所见，表中存储的所有语义和关系信息都保持不变；刚刚重组了。
一般来说，一旦达到表的最大大小，就知道表太大了，可能设计得更好。这在大型应用程序中尤其可能发生，在这些应用程序中，遗留需求导致表不断增长……同样，这通常是无法充分设计新特性的一个例子。

mysql有一个最大行大小。
因此，最好的选择可能是将表数据规范化为以下内容。

CREATE TABLE guidatatable (
    id INT UNSIGNED NOT NULL PRIMARY KEY AUTO_INCREMENT
  , col_row_position INT UNSIGNED NOT NULL 
  , col_text MEDIUMTEXT NULL
  , col_position INT UNSIGNED NOT NULL 
  , guidatatable_status VARCHAR(255)
  , KEY(col_row_position, col_position)
 ) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci;

这还处理mysql更好的最大数据包大小。
