Error al insertar datos #1118 - Row size too large

[pentergar]

Muy buenas, he creado una base de datos de la siguiente forma:

ALTER TABLE cw_product_codebar
ADD COLUMN code VARCHAR(5),
ADD COLUMN text1 TEXT(24),
ADD COLUMN text2 TEXT(24),
ADD COLUMN text3 TEXT(24),
ADD COLUMN text4 TEXT(24),
ADD COLUMN text5 TEXT(24),
ADD COLUMN text6 TEXT(24),
ADD COLUMN text7 TEXT(24),
ADD COLUMN text8 TEXT(24),
ADD COLUMN text9 TEXT(24),
ADD COLUMN text10 TEXT(24),
ADD COLUMN text11 TEXT(1000),
ADD COLUMN text12 TEXT(1024),
ADD COLUMN text13 TEXT(1024),
ADD COLUMN text14 TEXT(1024),
ADD COLUMN text15 TEXT(1024),
ADD COLUMN text16 TEXT(1024),
ADD COLUMN text17 TEXT(1024),
ADD COLUMN text18 TEXT(1024),
ADD COLUMN text19 TEXT(1024),
ADD COLUMN text20 TEXT(1024);

Y al rellenar los datos me genera el error:

#1118 - Row size too large. The maximum row size for the used table type, not counting BLOBs, is 8126. You have to change some columns to TEXT or BLOBs

No se donde puedo configurar la anchura de la tabla máxima, alguna ayuda?
