The thin wood of an oak table is a layer of thin wood chips cut from logs by a rotary cutting machine, slicer, or saw. The thickness of the sheet can vary from 0.6 mm to 6 mm, depending on the desired effect and quality. Then, the veneer will be glued to the core material (such as plywood, particleboard, or MDF) to make a flat panel, which can be used to make furniture. Veneer can also be dyed, colored, or painted to improve its appearance or match the core material.
Examples of common veneers used to make oak table furniture include birch, ash, pine, beech, and bamboo. These veneers can imitate the appearance and texture of hardwood or create a unique style for your dining table. 
Advantages and disadvantages of a  thin wooden dining table
A thin wood dining oak table has many advantages, which make it a feasible substitute for a hardwood dining table. Here are some advantages of a thin wooden dining table:
Cost-effective: the price of a wood-based dining oak table is lower, which can save you a lot of money. They require fewer materials, labor, and production time, and compared with solid wood dining tables, their demand is lower, and their supply is higher. Because of their light weight and small size, their transportation and installation costs are also lower.
Stability: the wood-based dining oak table is more stable, which can better maintain its shape and stability. They are less sensitive to changes in temperature and humidity and more resistant to deformation or cracking. They are also more resistant to moisture and sunlight, and can better prevent mold, mildew spots, or fading.
Multifunctional: The wood-based dining oak table is more multifunctional, which can create a variety of styles and atmospheres for your restaurant. They can imitate the appearance and texture of solid wood and create a unique style for your dining table. They can also be dyed, painted, or painted to match any color or theme you want.
Sustainability: Wood-based dining tables are more sustainable and can reduce the impact of furniture manufacturing on the environment. They need to cut down fewer trees and release less carbon dioxide and other greenhouse gases into the atmosphere during production and transportation. They can also use recycled or reused wood as the core material, which is easy to handle or recycle.
However, the wood-based dining oak table also has some shortcomings that you need to know. The following are some shortcomings of the wood-based dining table:
Difficult maintenance: the wood-based dining oak table is difficult to maintain, and it may not be repaired if it is damaged. They are more prone to dents, scratches, or cracks than hardwood dining tables, and may peel off, blister, or crack if exposed to water or a hot environment. They are also difficult to polish, repaint, or refinish, and they cannot be repaired with glue, nails, or screws.
Low quality: the quality of the wood-based dining oak table is low, and its service life is short. They are made of thin wood chips bonded to the core material, which may have poor quality and strength. They may also have obvious seams, joints, or edges, and may have inconsistent or artificial patterns or colors. Not real enough: Wood-based dining tables are not real enough, and they may lack the natural and organic aesthetic feeling of solid wood dining tables. They are made of wood-like materials, which may look fake or cheap, and may lose their original appearance or characteristics over time. They may not be unique or personalized enough, and their compatibility with other materials, such as metal, glass, or stone, may be poor.
