table
桯 centers on a table, specifically a flat surface used for writing or working.
桯 combines 木 (tree/wood) with 呈, which likely contributes the sound. The character refers to a wooden table.
The left side is 木 (wood), and the right side 呈 looks like a flat surface with legs. Picture a wooden table made from a tree.
For テイ, imagine a table set for tea: tea -> テイ, and the wooden table holds the teacups.
