Function reconstruct_table 

pub fn reconstruct_table(
    words: &[HocrWord],
    column_threshold: u32,
    row_threshold_ratio: f64,
    debug: bool,
) -> Vec<Vec<String>>

Reconstruct table structure from words

Takes detected words and reconstructs a 2D table by:

1. Detecting column and row positions
2. Assigning words to cells based on position
3. Combining words within the same cell
