The main point here is to use CSS style control in the <table> tag has a style= "table-layout:fixed", which is described as follows

Grammar:

Table-layout:auto | Fixed

Parameters:

Auto: The default automatic algorithm. The layout will be based on the contents of each cell. The table is not displayed until each cell is read and calculated. The speed is very slow
Fixed: An algorithm for fixing the layout. In this algorithm, the horizontal layout is based only on the width of the table, the width of the table border, the spacing of the cells, the width of the columns, and the table contents, and in the <td> tag, if there is no Word-wrap:break-word style, the contents of the table will show only one part. Look at the width of the table. The word-wrap description is as follows:

Grammar:

Word-wrap:normal | Break-word

Parameters:

Normal: Allow content to top open specified container boundary
Break-word: Content will wrap within the boundary. If necessary, word wrapping (Word-break) will also occur.
